When you have a ::after::marker, and you compare one against the other we ended
up with the wrong result because of the pseudotype stuff.
I think this is cleaner now that DoCompareTreePosition handles pseudos properly
(which is really the thing this was working around).

According to the procedure to update animations and send events[1] the UA should
update all timelines first and _then_ run a microtask checkpoint.
As a result, when we run callbacks for the finished promise on an Animation they
should see the fully up-to-date state of all animations, regardless of which
timeline they are attached to.
However, that is currently not the case since we run a microtask checkpoint
after updating each individual timeline.
This difference will become more significant later in this patch series when we
introduce another step--removing replaced animations--that _also_ should happen
before we run the microtask checkpoint (so that the promise callbacks always see
a fully-up-to-date state).
This patch makes our handling a little more in line with the spec. It's not
quite the same because it's possible there may be other refresh driver observers
that trigger a microtask checkpoint in between ticking the different timelines
but that case is expected to be rare and fixing it would require maintaining
a separate queue for timeline observers that we run after all other observers--
so it is probably not necessary to fix that case at this stage.
The test added in this patch fails without the code changes in this patch.

This enables destructors for tagged unions in cbindgen, implemented in:
* https://github.com/eqrion/cbindgen/pull/333
Which allow us to properly generate a destructor for the cbindgen-generated
StyleBasicShape (which now contains an OwnedSlice).
For now, we still use the glue code to go from Box<BasicShape> to
UniquePtr<BasicShape>. But that will change in the future when we generate even

I could add support for copy-constructor generation to cbindgen for tagged

Unfortunately, `EventChainVisitor` does not grab the `nsPresContext` with
`RefPtr` by itself. Therefore, there is no guarantee of the lifetime without
checking the origin when its subclasses are instantiated. This patch changes
it and subclasses to `MOZ_STACK_CLASS` since only `EventDispatcher::Dispatch()`
creates them in the stack with given `nsPresContext`. Additionally, it's
already been marked as MOZ_CAN_RUN_SCRIPT_BOUNDARY`. Therefore, the
`nsPresContext` instance has already been guaranteed its lifetime by the
caller. For making this fact stronger, this patch marks their constructors
as `MOZ_CAN_RUN_SCRIPT`. Therefore, nobody can create those instances without
guaranteeing the lifetime of `nsPresContext` and `dom::Event`. Note that
it may look like that `mPresContext` of `EventChainPostVisitor` is not
guaranteed. However, `EventChainPreVisitor` which gives `nsPresContext` to it
is also a stack only class. So, it won't be deleted before
`EventChainPostVisitor` instance.

We always include the combinator for pseudo-elements now (not including it was
just an optimization) in order to not match when nested pseudo-elements are
involved.
We could add a more generic check in `matches_simple_selector` like:
```
if element.is_pseudo_element() {
match *selector {
Component::PseudoElement(..) |
Component::NonTSPseudoClass(..) => {},
_ => return false,
}
}
```
But even that wouldn't be enough to make selectors like `:hover::marker` not
match on the `::before::marker` pseudo-element, plus that code is really hot.
So for now do the check on the `next_element_for_combinator` function. It's a
bit hacky but it's the best I could came up with...
While at it, simplify some checks to use is_pseudo_element() instead of
implemented_pseudo_element() directly.
Only the Rust patch as-is would make markers for ::before and ::after on list
items not show up, so we also need to switch ::marker to use ProbeMarkerStyle()
rather than ProbePseudoElementStyle(), since the marker should exist even if it
matches no rules.

Sorry for the vague commit message, but I haven't dug yet on why or how the
Android code is depending on this.
This call used to be part of nsPresContext::CompatibilityModeChanged, which
unconditionally called PresShell::EnsureStyleFlush.
This was not (in theory, at least) always necessary. There's there's no point in
ensuring a style flush is going to happen if styles haven't changed, and
CompatibilityModeChanged() didn't actually guarantee that the compat mode was
different at all before my patch.
Styles only change if the compat mode actually changes (since then selectors
become case-sensitive or case-insensitive), or more obviously when you insert or
remove the quirks.css stylesheet, and in that case ApplicableStylesChanged makes
sure that the flush happens.
Yet here we are, and not having that early call to EnsureStyleFlush, even in the
case there's no quirks mode or quirks sheet change or anything of that sort
(this happens even on XUL docs, which are always FullStandards) makes the first
(and only the first) browsing session in Geckoview have terrible scrolling
performance.
