This patch fixes two issues:
* The bottom corner of the new sidebar was never correct because of
a `padding: 2px` that was introduced later, but never compensated
for.
* The moment the toolbar is shown it's not a single-template dialog
any more. This implies minor style changes.

I run into this in some local test. There are two reasons this code
can be reached:
* When a wiki doesn't have the TemplateData extension, the
additional API call from line #154 will fail. But the original
search query succeeded. We have the `originalResponse` and can
return it. This makes the code behave as if the additional
TemplateData API call was never done.
* But what if the original search query failed? We still end in
line #183 – as we should. But this time it can't return anything
but undefined. This will be considered a valid, successful API
response. But it isn't.
There might be a better way to clean up this chain of promises.
This is the smallest fix I found.

Instead of using an object mapping namespace ids to if they have
subpages enabled or not, pass an array of the namespaces where
subpages are enabled, reducing the size of the configuration that

object value).

This was damaging the UX by causing the first parameter to be marked
as selected, but without reliably focusing it. For example, loading
a wikitext-template-wikitext multi-part transclusion would cause the
initial focus be given to the documentation link in the template
content header. After this patch, the focus will be at the top of
the page and tab will run down window functions and then through the
sidebar.

the focus in some situations when you press space. Still this patch
already improves the situation. Pressing space on both top-level

at all.

The most basic fix. The "outlined" flag is set to false for the

place.

We removed this line of code in a recent patch, but it turns out
it's still necessary in at least one situation:
* Make sure you have a multi-part template where the first part is
a wikitext snippet.
* Edit the template.
* Click the very first item in the sidebar.
Nothing happens. But the text cursor should be in the wikitext
field.
Another situation:
* Put the text cursor in the first wikitext field.
* Press shift + tab. Now a button in the bottom toolbar should have
the focus.
* Click the 1st element in the sidebar. Again, nothing happens.
The extra .focus() call is redundant in many situations. But it also
doesn't hurt to repeat it. It will just re-focus the element that's
already focused.

I realised these are vital information to make the buttons at
the bottom of the template dialog behave sane. It's still
possible to focus this page, even if it doesn't have a visible
item in any of the old/new sidebars. This is when these flags
are used to decide if the up/down/remove buttons should be
enabled.

Change-Id: I6ab709b856d110bfb37daa1592c0b6a99714aa25
The OO.ui.OutlineOptionWidget class does have an .isRemovable()
state. This is how OO.ui.OutlineControlsWidget decides if the
remove button can be used.
It appears like ve.ui.MWParameterPage forgot to mark required
parameters as not removable.
This makes some oddly specific code in ve.ui.MWTransclusionDialog
obsolete. Note how this class does not contain any other code
about "required" or other flags specific to parameters.
Note that one aspect of this patch will be visible in the old
sidebar: The trashcan will be visible on required parameters, but
disabled. It was hidden before. However, this actually improves
the UX. Hiding the trashcan made the up/down buttons jump around.
This makes it unnecessary hard to hit them. It also causes visual
distraction when navigating the list of parameters.
Let's stick to the upstream OOUI behavior.
The remove button still disappears when the only element in the
dialog is the template search widget. This is clearly an
entirely different state. (Don't ask why the up/down buttons are
not hidden. It was like this before.)

The behavior of the enter key in the new template dialog sidebar
is somewhat inconsistent. When pressing enter on the name of a
template it sometimes just doesn't work, but focuses something
else.
I realized this is because the message "The … template doesn't
yet exist." does not have a link. There is nothing to focus in
this element. The code just gives up and the selection returns
to whatever was selected before.
It works when there is a link in the template header. But this
is not even that useful.
Let's try to always focus the first parameter instead. The user
can still press Shift + Tab to focus the link to the template
page.

The previous patch I15aa2c0 (approved by UX) was incomplete. The
required indicator was still shown, depending on the skin.
This patch also reduces the amount of generated HTML when it
doesn't have an effect anyway. At the moment an empty <span></span>
is generated for _every_ parameter in the dialog. That's potentially
hundreds. But the element is only needed for deprecated and
(in the old UI) required parameters.
A missing space is added while we touch this code anyway. The
missing whitespace between label and indicator icon is confirmed to
be a bug by UX.
Styles that are the same on all skins are moved to the .css file
that's loaded for all skins. Missing word-wrapping for overly long
template parameter names (on the right side of the dialog) is added.
The position of the indicator icon was broken on Minerva the moment
a parameter name is a bit longer. Fixed by replacing `inline-block`
with `inline`.

This patch improves the error handling for when a user tries to add
a parameter which is either an alias of a existing parameter, the
primary name of a existing aliased parameter, or a name/alias of an
existing parameter which is shown with an override label.
The error message was modified to always refer to the conflicting
parameter using the same name that is has in the sidebar.
Example: A parameter named "Parameter B" is already present in the
sidebar under its alias "B". When a user tries to add "Parameter B",
the new error message will inform the user that the parameter they
are trying to add already exists as "B".

This partly fixes one of the issues mentioned in I97d77f4. The

As a reminder (not part of this patch): Pressing enter on the name of

when it is not.
* Make sure default values are mentioned.
* List individual `@cfg` options when it makes sense.
Note I don't list all options a class could accept (e.g. via all

how a class is actually used and list only these options.
Even then I don't list everything, e.g. unspecific options

We don't need to distinguish between these any more. Both are

the parameter doesn't change (for whatever reason, i.e.
because the parameter name was clicked instead of the

focus change.

The 'classes' property is a OOUI interface. Personally, I like
this code style better.
However. It appears like the code style in this codebase is
somewhat mixed. It looks like the top-level .$element always
uses .addClass(), while other code uses the 'classes' property.
Should we unify this?
Change-Id: I9ecd75e22d00f06ffd707f766dc9e8d748ff9a37
In JavaScript .split() behaves different, compared to PHP. In
PHP the last element contains the rest of the string. In
JavaScript the rest of the string is discarded. The limit acts
as if the array is truncated. That's why we can reduce the
number in
'foo/bar'.split( '/', 1 )[ 0 ]
to 1, as we are only interested in the element "foo".
The same code in the other class is currently not covered by a
test. But changing it accordingly should be obviously fine now.

Previously, when the tranclusion dialog was being resized, there was
a specific width at which both the sidebar was collapsed and the dialog
was downsized from "larger/large" to "medium". This resulted in the
dialog switching from fullscreen to floating, since the dialog's width
breakpoint for "medium" doesn't match our width breakpoint for mobile.
If the user continued to downsize past this breakpoint, then the dialog
would eventually switch back to fullscreen resulting in this weird
behavior.
A simple way to prevent this is to avoid changing the dialog's size
at all. Since we don't support collapsing the new sidebar (unless
already in fullscreen), we can just leave the dialog at the
"larger/large" size.

Any of these characters results in bad wikitext, when we accept
it in a template parameter name.
Instead of displaying an error message we simply block the
button, as long as the input is not a valid parameter name.
Coming up with a message is not really worth it, I would
argue. Users typically don't have a reason to use any of these
characters. This is super rare. And even if, the behavior of
the widget is not hard to understand, I believe.

hidden in the .addResults() method.

I tried hard to come up with the best possible names. Some of the
criteria I used:
* Longer and more unique is better. This makes it much easier to
e.g. search for the event name.
* The term "part" should only be used for top-level parts. While
template parameters have a unique id, they are not a subclass
of …TransclusionPartModel and therefor not "parts".
* BookletLayout manages "pages" via "page names".
* The page names of top-level parts are identical with the part
id, see ve.ui.MWTemplateDialog.getPageFromPart.
* The page names of parameters are identical with the parameter
model id, see ve.ui.MWTemplateDialog.onAddParameter.
Some code knows parameter ids, but not what pages are. Other code
knows page names, but not what parameters are. The transition
currently happens in the …OutlineContainerWidget. We might want
to move this point up to the …TemplateDialog. But I would argue
this is good enough for now and can be changed later, if needed.

return to the original position with shift+tab. Unfortunately
this is not how the SelectWidget works. The moment the

Yes, this is confusing at the moment. Following patches will
rename, merge and split a lot of these events to be much more
self-explaining.

We forgot to remove this in I319896a. The individual
…TransclusionOutlineParameterWidgets don't fire this event any
more. Instead this is done by the …SelectWidget.

Note there are currently two different code paths utilizing two
different events. The existing event handler actually changes
the selection of the top-level part in the sidebar (the
corresponding template name turns blue). The new event handler
highlights a parameter (it turns gray). This is currently
intentional (partly because of a bug in OOUI). I will try to
merge these code paths, if possible.
Please test, and if it works fine from the user's perspective,
please merge it as it is for now.

Proof of concept: while flex is – well – flexible, it feels like
this should be possible with some good old block containers and
margins. It's pixel-perfect in my test.

This fixes a few style issues:
* The buttons that represent top-level elements have a proper
2px focus rectangle again. Back to the OOUI default.
* The list of parameters does have a 1px focus rectangle all
around. Intentionally thin because there is a 2nd level of
keyboard navigation (via cursor keys) in this element.
* All these focus rectangles look the same in Firefox. Before,
it was a thin dotted line on the parameter list.
* Parameters with long names don't wrap on a 2nd line any more.
I believe this was working before but got lost in I92e8fd2.

When I press the button to expand the input field for
undocumented parameters, it needs to be focused. Otherwise I
have to click it manually all the time.
We probably forgot to list this as an acceptance criteria when
working on Ic5dcd36.
This also replaced a bit of JavaScript with CSS. I do this
mainly because I found the mixture before (one piece was
hidden via JavaScript, another via CSS) a bit confusing.

This makes sure the corresponding top-leve part is selected in
the list on the left when navigating the main area on the
right.

This comes with a few significant changes:
* A whole bunch of places in the code that focus and highlight
an element in the old sidebar consider the new sidebar now.
* Same when e.g. the toolbar at the bottom needs to know which
part is selected. This is read from the new sidebar now.
* To make this possible I had to merge the small helper class
we introduced in I7bc73cc back into the dialog.
It's helpful to understand how the event flow works:
* You click a template name. This does nothing (does not select
the element). It only triggers an event.
* The event is catched by the outer container that manages
all parts. From there all elements are unselected, and one
selected. This call is internal and should not trigger
another event.

This is mostly, if not exclusively visual, at the moment. The
actual state is still managed by the old sidebar.
I made the element OptionWidgets for convenience. This gives us
all the functionality we need (primarily setSelected and
isSelected), without to much clutter. However, I didn't made
the container a SelectWidget. This comes with to much stuff we
don't need at this level, e.g. cursor key navigation.
