The only places where this dialog is used now will have the same
button labels and format. We want to use "normal" destructive here
so no additional "primary" styling.
It seems that the focus on the action will only be applied
automatically when it is primary. So extra code is needed.

From the user's perspective nothing changes. A template without
parameters doesn't show anything. (Technically there was an empty
<div>, but it doesn't do anything.) The moment the first parameter
is added the required sub-widget is created and available from there
on.
This saves loading time and memory, especially when a multi-part
template contains many templates without parameters.

From the user's perspective this is the same as before: When a
template doesn't have any parameters, there is no search field. The
moment the first (undocumented) parameter is added the search field
appears.
This is just delayed now. The widgets are only created the moment
they are actually needed.
This saves loading time and memory, especially in a multi-part
transclusion with many zero-parameter templates.
This also makes it a lot easier to change the minimal number of
parameters from 1 to e.g. 4.

The "Add parameter" page always starts collapsed. Even if a template
doesn't contain anything but this. But most of the content isn't
visible, unless the user presses the button. It's not only a lot of
content, it's also rather expensive, including .parseDom(),
LinkCache.styleElement(), and ve.targetLinksToNewWindow(). This adds
up in large multi-part transclusions. In an example with 200 parts
the total blocking time goes down from 2.9s to 2.4s. Which means this
is not a major bottleneck, but still worth it.

This sorting algorithm was introduced via Ic6bc348 (T274544). Note
there is no index parameter in the .onReplacePart() handler at this
point. When a part was moved, it was removed and simply appended
to the end. The additional sorting was needed to move it back to the
correct position.
This changed a few days later via Iafe29f1. There is now an index
parameter. The .onReplacePart() handler does the same as before, but
puts the part at the correct position right away. The additional
sorting is pointless since then.
The removed code alone is responsible for 1/3 of the total blocking
time when the template dialog opens.

This is only relevant with the old design. It's only noticable when
a field shows all 3 action icons: info, raw wikitext mode, and
trashcan. The last icon can wrap to the next line when the screen
is very narrow.
I tried to apply nowrap, but this causes other style issues.
Removing the arbitrary width allows the action container to be
as wide as it needs to be. I can't tell why this restriction was
there. It is in no way necessary, as far as I can see. I can only
guess it's a temporary artifact from when the dialog was designed.

MWExpandableContentElement objects do some quite expensive

In OOUI the close button is always on the left side. See

The CSS hack to move it to the other side doesn't work and must be
removed. You can see the problem the moment the text is longer (which
can easily happen in translated versions).
I tried to come up with a more official way to move the button to the
other side, but gave up. One way is to replace the existing
flags: [ 'safe', 'close' ]
with:
flags: [ 'primary', 'close' ],
framed: false
But this causes other style problems. Let's remove the bogus CSS

ARIA-selected only works on specific elements/roles. I tried several

that role did not work very well in FF with NVDA. It also should only
be used as direct child to a listbox e.g. with several children.
The next role that's working with ARIA-selected that seemed fitting
is the gridcell. It's still a bit hacky but works well in IE and FF
with NVDA. I suspect that that's pretty good coverage already then.

Load errors are already handled in the MobileFrontend part of the
mobile visual editor, by this code:
66c55573e5/src/mobile.init/editor.js (L375-L387)
// Wait for the data to load before we show the editor overlay
overlay.getLoadingPromise().then( function () {
...
}, function ( error, apiResponse ) {
// Could not load the editor.
(1) overlayManager.router.back();
if ( error.show ) {
// Probably a blockMessageDrawer returned because the user is blocked.
document.body.appendChild( error.$el[ 0 ] );
error.show();
} else if ( apiResponse ) {
(2) mw.notify( editorOptions.api.getErrorMessage( apiResponse ) );
} else {
mw.notify( mw.msg( 'mobile-frontend-editor-error-loading' ) );

Compared to our code:
ve.init.mw.MobileArticleTarget.prototype.loadFail = function ( code, errorDetails ) {
...
(1) this.overlay.onExitClick( $.Event() );
(2) mw.notify( this.extractErrorMessages( errorDetails ) );
};
The lines marked with (1) and (2) do basically the same thing. And
the function parameters "error, apiResponse" and "code, errorDetails"
are actually the same objects, just with confusingly different names.
This causes the popup with error message to appears twice (although it
isn't too obvious, since the two popups appear in the same place, so
only one is visible), and also causes bogus data to be sent in event

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.

The TemplateData extension is not limited to the Template: namespace.
And even if pages outside of the Template: namespace typically don't
have TemplateData information, the API is still able to automatically
extract parameter information from every page.
Or:
It's rare that a page outside of the Template: namespace is used as
a template. But if it is, this is not a mistake. The code here in
VisualEditor should not try to be "more clever" than the user is. If
this is what the user want's to do, let's not block them.

press one of the keys the focus is stolen by some element on the
right side of the dialog. This makes it impossible to e.g. press
Ctrl+Shift+Down multiple times. The idea is to work on this in the
next patch.

Reasserts scroll and highlighting when toggling the sidebar, in the
case that the other panel is hidden (narrow-view mode).
FIXME: Doesn't reassert focus because the page.focus() and
bookletLayout.focus() methods don't seem to work, maybe the bug is
especially prominent when the item to focus was already marked
active.
FIXME: Stopped working for right-to-left sync on wikitext elements.
This is a less common use case and can be addressed in follow-up.

… obviously only to methods that are meant to be private, i.e.
only called from within the class (and possibly tests).

The .onUpdateOutlineControlButtons() method doesn't describe what it
actually does. This issue was introduced in I9c5478a. (Intentionally,
to not make the patch to complicated.) Let's continue to rename
things to be a) unique and b) honest about what they do.
This is an alternative to I8d98e61.

I can't really tell what insight we get from the word "container".
Every widget is a "container" in some sense, isn't it?
This widget is just _the_ outline, I would argue.
Other suggestions?

This prevents multiple highlighting, which was possible to achieve by clicking
sequentially in the input fields of two parameters from different templates.

This is bad for multi-template transclusions, where we focus the
first parameter of each template ending with the last. It's also
inconsistent, we don't do the same for wikitext chunks.

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.

Most block-level things that can be interacted with by clicking have a
highlight. Categories don't, and that makes it harder to discover that
you can edit them.

The weird auto-scroll feature is described in T289043#7297679.
This also fixes T291381 different than I393a2b1. Only one of the
patches should be merged.

AddPart in the resetDialog also triggers replace part
so this call could be removed there.

This is mostly re-arranging existing code. Actual changes made:
* Remove the message that claims a template can't exist. We can't
really know this.
* Instead show the message about "modifiers" in cases where curly
braces and other wikitext syntax is involved.

The titles in the link cache do not include subst: anymore so to see
if these pages exist we need to use the same link title used in the
query.

This code was introduced in I8fafee6. I can't tell any more what
the "bug" mentioned in the commit message was. Let's get rid of the
duplicate code path, see if we run into regressions and deal with
them one by one. That's much easier to handle than keeping this
confusing code path around.
Note this "focusin" event handler was actually re-implementing
parts of the upstream BookletLayout, namely
OO.ui.BookletLayout.onStackLayoutFocus().

I was (again) wondering why the try-catch is there. But it's actually
needed. Now covered by a test.
