According to the compatiblity standards to give Grade A support
for modern browser versions not older than 3 years, we do not need
these workarounds anymore.

Mousemove events seem to bubble up and can trigger unwanted hover
effects when the tooltip is appended to the pointer container.
This regression was introduced in the patch that supports tabbing
into the tooltips in I75ef7c32fb105526552eac387ff5a5bda8eefe1b

Adds two handlers to make sure the popup is closed when the focus
moves away from either the pointers or contents of the a popup.

This is obsolete since I75ef7c3 where we had to replace the
`font-size: 0.8em` with a fixed 13px.

This was removed in I75ef7c3. Turns out it's needed for the
highlightable elements in the popups (e.g. when highlighting all
edits made by the same user). The text row in the popup gets a thin
gray border. This border needs some padding on the left.
The solution is to make the CSS selector more specific so it can
win over the problematic selector in Vector.

The pointer click and revision click handlers did almost the same
and the former was able to handle events from the latter. I merged
them and could then shortcut some code.

I'm not sure why it was done this way. Probably because it doesn't
make an actual difference from the user's perspective. My motivation
is: When we already called the code that auto-expands the
RevisionSlider UI then it doesn't make much sense to give the user
a keyypress handler that does the same a second time.
Possibly even related to T342556?
This patch also contains a few small, unrelated code cleanups.

Turns out this code can only ever access a single underline: The one
it owns and can access via it's own this.$html property. One of the
two jQuery selectors always turned out empty, and calling .css() or
anything else on an empty jQuery collection just doesn't do anything.
This patch also contains a similar, but technically unrelated
cleanup in the init code.

Two almost identical pieces of code, both adding revisions to the
list.
There is a 3rd one that prepends revisions. I leave this untouched
for now.

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.
