When the user uses the keyboard to interact with the slider, the
revisions can changed by moving the pointers with the arrorw keys.
In that case the pointers have keyboard focus. To allow tabbing
into the popup from that position, the tooltip needs to follow the
pointer in the DOM. That's what's done in this patch.

It took me a while to come up with a solution for this, but there
are several things that seem to trigger the showTooltip method a
bit to often.
Tooltips can be triggered either by the handlers that deal with
mouseenter and mouseleave events that also trigger revision high-
lighling. But tooltips can also be triggered when you use the
keyboard or the mouse while dragging sliders.
The mechanics on what's highlighted and what's triggering a popup
are a bit weiridly setup and there could probably be a major re-
factoring done to make things clear ( for example the show popup
method also highlights the revision but the highlight revision
mehtod does not ). I had a quick approach to fix that, but it's
not too easy.
Another issue is, that some events fire off a delayed popup close
mechanism. So the solution here reads like:
If you are triggered to show a popup, and that popup exists
already, stop the delayed popup close mechanism and bail out.

The plain wikitext comment is apparently not used for anything,
anywhere. It was for some reason used for an "is empty" check. But
we can do the same with the `parsedcomment`. I checked and an empty
comment doesn't result in something non-empty like `<div></div>`, but
stays as an empty string.

This code was designed for the left/right cursor keys. But it
currently triggers on all keys. This causes confusing behavior when
tabbing through the UI. This code also triggers on tab/shift+tab,
which can be visibly seen when the wrong popup opens. It also
triggers on enter, which feels like it's intentional, but is nore a
happy accident.
Especially note how the buildTabbingRulesOnKeyUp handler directly
below does the exact same: It only acts on left/right, but no other
key.
We intentionally keep the existing (even if bogus) behavior for the
enter key. To be replaced with something better in a later patch.

I removed this aria-hidden, because the RevisionSlider as a whole
can be accessed with the focusable button that expands the UI.
Elements that are focusable should not be aria-hidden.
screenreaders in general will allow interaction with these or even
might show unpredictable behavior.
Screenreader and keyboard support for the feature is not good but
this aria-hidden is useless and wrong at the moment.

Reintroduces IIFE closures in test files because variables were
declared in the global namespace, and "const" now causes hard errors.

I'm not sure why it was done like this. It looks like we can skip
both the extra conditional as well as the extra function scope.

This is certainly not an actual fix for anything. But it makes any
resize issue look much less broken and much more bearable. I think it
is helpful to have this extra safety in place even after we properly
fixed the issue.

This is best-practice, as far as I can see. It doesn't make a
difference in terms of what is stored in the database. false,
the number 0 and the string "0" will all be stored as "0" in the
database. More precisely: These values will not be stored because
they are all considered equal to the default value by
UserOptionsManager::isValueEqual().
It makes a difference in terms of what is send to the browser. The
keyword "false" is 5 bytes while "0" is only one.

Due to some change in the test setup, possibly related to the new
Vector skin, the slider now has more space and the need to scroll
triggers at a later point.

According to https://api.jquery.com/html/ a jQuery object is not
supported in .html() although is works.
The .empty() is needed to avoid multiple sliders on resize.
