This installs a series of safety nets:
* The selector [href*="#"] skips links without a fragment.
* It's still possible that a fragment exists, but is empty.
mwTitle.getFragment() checks this.
* The gateway does not assume the element exists, but checks this first.
If there is no such element, the gateway aborts the request in a way
that no error popup is shown. This is currently only possible with the
`{ textStatus: 'abort', xhr: { readyState: 0 } }` response as seen in
this patch. We might need to introduce a new, more clean way to silently
quit a fetchPreviewForTitle() call.
* The test for the reference gateway finally covers the scraping code.

Including tests for all situations.
I believe it is impossible or extremely hard to actually abuse any of
these places. All these data are not extracted from the current page, but
delivered either by MediaWiki's api.php or a RESTful endpoint, as
configured via $wgPopupsGateway and $wgPopupsRestGatewayEndpoint. A
possible attacker would need to write it's own endpoint (which must either
run on the same server or somehow ignore the CSRF token), and set the
value of mw.config.values.wgPopupsRestGatewayEndpoint on the client to
this endpoint – which requires just *another* attack vector to be able to
do this.
It's "the right thing"(tm) to escape all this anyway.
I found two possibly relevant security reviews of this extension, T88171
and T129177, resolved in 2015 and 2016.

This will affect all links, including [[Other page#Fragment]] for
example. But it will not have much of an effect there. The mw.Title
class is able to understand strings like "Other page#Fragment". All
old code calls title.getPrefixedDb() on the result. This will *not*
include the fragment. Only the new code will use title.getFragment().
I made sure this does not affect regular page previews, even when the
link is something like [[Other page#Fragment]].

I tried hard to keep the CSS as small and robust as possible. The
icon will be align with the text by adding a negativ margin. With
that we also decided against using RTL and LTR specific icons that
are positioned at the edge of the canvas for now.

I guess both is fine: either having the default in the gateway (as it
was before), or in the renderer (as this patch proposes). I, personally,
feel better with having it closer to where it is needed. This way it's
not possible to accidentially deliver a model object with an empty title.
The renderer will catch this.
At the moment we don't know exactly how we will fetch other titles (e.g.
"Book").
This change is split from I15611a4 where it was a little misplaced.
It also includes a test for the default fallback title.

even if not critical in that case.

Special characters that have a meaning in one of the many different input
formats jQuery accepts must be escaped.
The real-world use-case are references like <ref name=":1"> with a colon.
But it's many more characters that need escaping. See
http://api.jquery.com/category/selectors/
Note this patch misses a test. I already uploaded I9ec57e0 to fix the
currently incomplete tests. But I can't make it work. How do I create an
element in the test environment so that jQuery finds it?
I suggest to merge this and continue working on the tests later, because
this is currently one of the most annoying issues that makes all testing
unreliable.

This is documented at http://usejsdoc.org/tags-type.html, but not in many
other places, especially not in the JSDuck documentation.
The {!…} syntax means "can not be null". This is the default anyway.
The {?…} syntax means nullable. In a few situation is was used when a
parameter can be undefined. I decided to remove it everywhere and replace
it with {…|null} when appropriate, because this is much more explicit. Less
syntax to remember.
Note I'm intentionally not using the […] syntax when a parameter is followed
by non-optional parameters. Actually skipping a parameter in such a situation
would mess the parameter order up. Having optional parameters not at the end
is sometimes used as a feature in JavaScript code, but not in this codebase,
as far as I can see.

It's not exclusively about page summaries any more.
We had a few suggestions in mind:
* get, fetch, request, or issueRequest. But I feel these are all to
generic and don't describe well what the method does. As a reminder:
It expects a Title object and returns a promise, which returns a
PreviewModel object, which contains an HTML "extract".
* fetchPreview? I feel this can still mean to many things.
* fetchPreviewModel? But we don't really need to repeat that it will
return a model object.
So I went for fetchPreviewForTitle. What do you think?

This adds support for preview popups on reference/footnotes from
the Cite extension. For that a new preview type was introduced and
integrated into the existing structures.
The essential starting points were this code comes into action are
added behind the feature flag introduced in the previous patches.

Most of the code is exported because is is tested separately. But
these are all tested via createPreviewWithType(). I think it's just a
minor mistake to have these exported.

This is split from the current draft patch Ie0ccb03. This is part of a
series of very small patches that prepare the code for new types of popups.
We decided to not add code for other types of popups to the existing
createGateway() function, but introduce new files and functions instead.
Renaming, for example, the existing `gateway` variable name will make it
much more obvious which of the future gateways does what.

This became an issue after the patch Ifa56d41 (part of T206323) removed
some hidden <span> and replaced them with title="…" tags. The CSS selector
in src/index.js get's active on all <a> elements that have a title="…"
attribute. This is now the case for all references that are used one time
and have their ↑ (or ^ on the English Wikipedia) linked.
I realized this is really only an issue for these ↑ links.
The more general issue described in T198652 still holds true, but becomes
less urgent with this bugfix.

Storybook.js provides a framework for
viewing and working with UI components.
https://storybook.js.org/
This patch adds the Storybook.js UI library to Popups for
the purposes of viewing multiple previews at once.
This enables viewing page previews in the following states:
- with thumbnails
- without thumbnails
- with SVG thumbnails
- with narrow thumbnails
- with white background thumbnails
- in RTL languages
- in non-latin languages
- disambiguation popups
Storybook also allows users to change the image or text
of a popup through a GUI.
This patch sets up Storybook as a "mini" repo inside
the.storybook folder with a seperate package.json file
to avoid incompatibilities with the current webpack/babel
(or even Node) versions used in the Popups repo.
Storybook requires at least Node v8.3 to run.
(an .nvmrc file with 11.3.0 has been added to the .stories dir).
To start:
`cd .storybook && npm install && npm run start`.

Copy learnings from MobileFrontend's Webpack configuration. If nothing
else, the files are more consistent and easier to diff. When the change
to rename source maps is excluded, the build products are identical.
The following changes were copied:
- DRY up the output directory and source map extension as variables. For
the latter, rename the source map from ".json" to ".map.json". Without
renaming, the build products are unchanged.
- Reduce verbosity. Only report warnings and errors.
- Fail to build when an error occurs.
- Update ordering and add comments for easier reasoning and diffing with
MobileFrontend.
