With splitting `HandleEvent()` a lot, it becomes more difficult to keep
managing each set of calling `PushCurrentEventInfo()` and
`PopCurrentEventInfo()`. So, `EventHandler` should have a helper class
to push and pop current event info into/from the stack.

By allowing the creation of StrongWorkerRefs in the Canceling state we
ensure that IPC will not fail and lead to crashes.

The calculation of aOverflow rect for a placeholder contained in a transformed
stacking context didn't take the transform into account, leading to an incorrect
rect which artificially inflated the calculated rebuild region.

The test expects that video is visible. The test needs to wait until the video element becomes visible. And appending a video element to document with loading the test video triggered 'mozentervideosuspend' event. It caused the test failure.

This patch avoids a potential division by 0 (one that's unlikely to be
triggered by real content), for correctness and robustness.
This patch isn't really changing the logic, because the newly-guarded code is
already guarded by a "length < sum" check, and "length" is expected to be
nonnegative [1], which means "sum" would already have been nonzero in cases
where the existing strict less-than comparison returned true.
[1] One special case where we can have negative `length` values here:
if this is an outline with an `outline-offset` that is sufficiently negative
to entirely cancel out the outlined element's border-box size, then that can
produce a negative `length` (i.e. the outline box will have a negative size,
conceptually). In that scenario, we were previously dividing by 0 here and
working with bogus huge/infinite negative values as a result, but we should
not do that.

This adds test which reproduce the failure as well as the fix. Essentially,
if we hit the edited case in SessionStore with `tab` equal to `tabbrowser.tabs[t]`,
we remove the tab and then try to pin it, which obviously blows up.
Note: the additional method in SessionStore.jsm was largely to get around
complexity requirements inside restoreWindow. Cleaner solutions welcome.

When we open firefox with pinned tabs, we first paint a window with
one tab open, and then that tab gets displaced after the pinned tabs
come in. This aims to ensure that our first paint contains the
pinned tab, so that we don't have tabs moving around after first
paint.

This patch addresses remaining test issues when pref'ing on. These are tests that
previously ran some tests in private contexts that now require the use of incognitoOverride.
This also fixes an xpcshell test wrapper to set the permission when overridden.

The way we control APZ zooming in WebRender is by inserting an animation
property placeholder on a WR stacking context, and then having APZ
update the animation transform value with the proper matrix at composite
time.
Previously, the stacking context being used was the rootmost
stacking context in the content process. However this doesn't work for
zoomable content in the UI process (e.g. about:support), and after
recent changes, also wraps display items that should not be affected by
zoom (e.g. scrollbars or the background color item).
This patch moves the animation property placeholder so that it
corresponds to the newly added nsDisplayAsyncZoom display item, which
corrects both of the above problems and is conceptually in line with the
desired behaviour.

U2F support, behind the `security.webauth.u2f` pref and exposed by `dom/u2f/U2F.cpp`, was broken when using Windows Hello, as the correct options for compatibility weren't set. This patch sets up Windows Hello to handle U2F-protocol backward compatibility properly.

This also adopts the resolution from [1] while at it, making letter-spacing
compute to a length, serializing 0 to normal rather than keeping normal in the
computed value, which matches every other engine.
This removes the SMIL tests for percentages from letter-spacing since
letter-spacing does in fact not support percentages, so they were passing just
by chance.
