When the user dwells on a link and there's enough room to display a
preview above it, then the preview should rest atop the link rather than
above the mouse.

If the user CmdOrCtrl+Clicks on a link, then the link will remain
focussed. If a preview is shown, clicks another element on the page, and
then there'll be no token to include in ABANDON_* with.

I09d8776 introduced a bug in the eventLogging reducer where reducing
LINK_CLICK would remove any accumulated interaction state but not close
the interaction.
Update the associated tests so that they correctly test the reduction of
this action.
Bug: T162924

... the interaction.
Following on from Iccba3c4c, LINK_CLICK shouldn't be considered the end
of an interaction because the link or preview can still be abandoned by
the user. Unlike ABANDON_END and LINK_DWELL, therefore, LINK_CLICK
musn't destroy the interaction but indicate that no more events should
be enqueued for the interaction.
More concretely, if the user has clicked the link or the preview, then
a "dwelledButAbandoned" or "dismissed" event shouldn't be logged.
Changes:
* Distinguish between "finalizing" and "closing" an interaction, where
the latter is the current behavior of ABANDON_END, LINK_DWELL, and
LINK_CLICK, in the eventLogging reducer and associated tests.
* If the interaction is finalized, then either the "dwelledButAbandoned"
or "dismissed" events shouldn't be logged.

MediaWikiGadgetsDefinition does some basic gadget name sanitization
and we have to do the same when checking "is gadget enabled for user"
Changes:
- sanitize gadget name same way as
MediaWikiGadgetsDefinitionRepo::newFromDefinition() does.
- add try{} catch() when loading gadget as getGadget might throw an
exception

As noted in T160406, the only QUnit tests that requires a running
MediaWiki instance is the test for mw.popups.processLinks. The function
itself is isolated from the rest of the codebase.
Now, as noted in T162876#3182198, during boot the
ext.eventLogging.Schema module is loaded asynchronously with
mw.loader.using. Since boot is unconditional and happens ASAP this
happens when the tests are loaded and run.
In the short term this can be avoided by not making the tests depend on
the entire codebase. The long term solution is laid out in T160406.
Supporting changes:
* Bundle assets with webpack@2.4.1.

... in the eventLogging reducer.
Like ABANDON_END, the LINK_CLICK should be considered the end of the
interaction in the context of the EventLogging instrumentation, i.e. no
events should be logged after the user clicks the preview or the link.
See T159490#3172692 for additional context.

Like the FETCH_COMPLETE and ABANDON_END actions, the PREVIEW_SHOW action
was delayed but not conditionally reduced. As ABANDON_END is delayed,
there's a potential for a race and if ABANDON_END is reduced before
PREVIEW_SHOW, then there's no interaction to reduce the action into,
which causes an error, e.g. T159490#3165276 and T162373. Making
PREVIEW_SHOW require a token stops the error occurring in this scenario.
An alternative would be to clear the timeout created in
ext.popups.Preview#show in #hide. However, this would be inconsistent
with actions#fetch and actions#abandon.

Mirroring all other actions that are dispatched after some delay, add
the token to the PREVIEW_SHOW action.
Supporting changes:
* Pass the token to ext.popups.Preview#show so that it can be passed to
actions#previewShow.

... instead of using the active element.
In the case of the eventLogging reducer, this fixes scenario 4.1 from
T159490#3150331, which was caused by late FETCH_COMPLETE actions being
reduced regardless of whether interaction had been finalised or a new
interaction had started.

I6d9ff52b introduced a regression where if a logged out user clicks the
settings cog then an error is thrown.
For now, passing the event to the behavior for further processing is
required. However, it's clear that this makes the
ext.Popups.PreviewBehavior abstraction leaky.

We have to be careful about the namespaces here, and then we don't
need the awful `.html( .html() )` hack. (I honestly have no idea
why that even worked for some browsers, it really shouldn't have.
The comment next to it is wrong.)
* Construct the 'svg:svg' element with the right namespace
* Set 'xlink:href' attribute on 'svg:image' element with the right namespace
Doing this correctly makes the thumbnails work in Opera 12, and it also
works as before in (at least) Chromium 57, Firefox 53, IE 11 and Edge.
I can't find out what version of Safari the other hack here was
supposed to apply to, but the code was wrong in both cases, and the
hack was mistakenly also applied to modern Chromium.

Require that two promises are resolved (or one is rejected) before the
FETCH_COMPLETE action is dispatched. The first promise represents the
gateway request and the second represents an arbitrarily long delay. If
the first resolves before the second, then there'll be a delay until the
second resolves; whereas if the first rejects, then there's no delay.

The delay/timeout logic in actions#fetch will require more than one wait
call, for example.
Changes:
* Update the stub created in setupWait to store all deferred-promise
pairs and update the integration tests so that they don't use the stub
accidentally.
* Remove all references to the waitDeferred/waitPromise properties.
* Fix tests that relied on the waitDeferred/waitPromise properties being
available regardless of whether wait had been called.
* Update outdated or brittle - in the sense that it didn't reference
constants but their values - inline documentation.

Mixing in the delay was introduced in If3f1a06f so that the total RTT
for an API request could be calculated. Now that the FETCH_END action is
dispatched when the gateway request ends and not when the preview model
is resolved, this additional information (state) is redundant.
Change-Id: I7e6ffe0945ffedd9425525fa7da855e729d50b77
Ideally, the preview model is resolved after 500 ms, regardless of
whether the internal gateway takes 100 or 300 ms. Given this, there's an
important distinction to be made between the "fetch" ending and it
completing and their associated actions.
Changes:
* Dispatch the FETCH_COMPLETE action when the preview model is resolved.
* Update the reducers accordingly.

If the user has disabled PP via the settings dialog or they aren't in
the experimental condition, then link titles shouldn't be emptied.
Because this behavior has to respond to the user enabling/disabling PP
within the same page session, change the linkTitle change listener
rather than conditionally registering it.

Binding the behavior to the preview before it's shown means that the
application will respond to user interactions with the preview even
though it's transparent.

If the user abandons link A (or preview A) and immediately dwells on
link B, then log a "dismissed" or "dwelledButAbandoned" event.
In this context, "immediately" means before the ABANDON_END action is
dispatched, which, currently, is 300 ms after the ABANDON_START action
is dispatched.

For now, mirror the interaction modelling in the preview reducer in the
eventLogging reducer to handle the user either:
* Repeatedly dwelling on and abandoning a link.
* (Repeatedly) moving their mouse between the link and the preview.
This fixes scenarios 1, 2, 5, and the general issue from T159490.

Step 1 of T161284. Given that the median API response time (as measured
by the client) is ~115 ms [0] and the API response is artificially
delayed so that the preview starts fading in at 500 ms, we can increase
the API request delay to 150 ms without affecting the current UX while
decreasing the number of incidental HTTP requests triggered by the user
glancing their mouse over a link to another page.
