This is in preparation to disable (but not remove) support for these customizations
by default. We want to avoid scanning for these files on start-up, but also don't want
to make our users jump through a pref-flipping hoop to get their customizations back.
So we'll detect those files and flip the pref for this release. For the next release,
we'll not load those files unless the pref is flipped.

Before this change, only elements inside the shadow root tree were scanned for the

inside a shadow root can start a drag for an element containing the shadow root.

The patch in bug 1507744 was not sufficient by itself, as the line-breaker could still accumulate a single "current word" across a text-run boundary, and then a single word-break value would be applied to it. We need to flush the line-breaker when word-break changes, so that each part of the word will have break opportunities set according to the appropriate value.

In order to show all popups on Wayland we need to set popup parent runtime for popups which don't have
fixed parent. For instance popup menus (fired after right button mouse click) can be issued on top of another popup
and we need to follow that connection on Wayland.
We track all open (active) popups to:
- close all visible tooltip windows when we're going to open another tooltip
- close concurrent popup on the same level when a new one is about to open
- get latest active popup as a parent for a new tooltip windows
- get latest active popup as a parent for a new popup menu without fixed parent

The test itself is reasonable, except that it reads scroll positions
from the main thread. With APZ enabled we need to flush any pending APZ
repaints before reading these scroll positions. So changing the
waitForAllPaints to the APZ-flushing variant makes that happen, and the

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.

Typically this would be handled by the visible region of the layer
changing. However, since we build the container layer for the filter
item directly the visible region doesn't get set or checked. As a
shortcut to using more of FLB we just ensure the building rect hasn't
changed.
The situations under which this bugs shows up are somewhat rare:
- The filtered item needs to be in transform so that it's bounds
are not changed by scrolling.
- The filtered item needs to contain items that change their drawing
depending on the building rect. In this case an image with downscale
on decode.
- The filter needs to be unsupported by WebRender.

The comment in nsDisplayTransform::GetTransformForRendering() clearly
says that |aOutOrigin| should return the same offset as GetTransform().
GetTransform() will pass the offset to GetResultingTransformMatrix()
which will round it in many cases to avoid subpixel blurry rendering.
But GetTransformForRendering() doesn't take this rounding into account,
thus contradicting the intent described by the comment.
This rounding is important to keep subpixel behavior consistent with
or without webrender enabled. Currently, SVG will be rendered blurry
in some cases if it's at a subpixel position. After fixing the problem
in non-webrender case, the strange blur still occurs in webrender case.
It turns out to be caused by this inconsistency.

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.
