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.
I'm calling it a day for today, will investigate as time permits in bug 1544185.

They are debug build only methods. So, callers of them shouldn't be marked
as `MOZ_CAN_RUN_SCRIPT` only for them. Therefore, `MOZ_CAN_RUN_SCRIPT_BOUNDARY`
must be better.

First of all, we should mark `nsIPresShell::FlushPendingNotifications()` as
`MOZ_CAN_RUN_SCRIPT` as soon as possible. Therefore, I'll mark all its callers
in `PresShell` as `MOZ_CAN_RUN_SCRIPT` first.

This patch makes accessible module use `mozilla::PresShell` directly rather
than via `nsIPresShell`. Additionally, renames `DocAccessible::PresShell()`
to `DocAccessible::PresShellPtr()` for avoiding conflict with using
`PresShell` in it and its sub classes.

Then, renames `TabChild::GetPresShell()` and `TabChild::GetDocument()` to

In the case where scroll-snap-type is specified for the scroll container, the
scroll-padding is also factored into in ScrollFrameHelper::ComputeScrollSnapInfo
which is called via ScrollFrameHelper::ScrollToWithOrigin. It doesn't double
the scroll-padding value, but it's actually redundant, we should avoid it.
We could separate the functionality of ScrollToWithOrigin, one is to scroll
to a given element, the other is to scroll to a given position. The former will
be used for Element.scrollIntoElement and relevant stuff, the latter will be
used for Element.scrollTo and relevant stuff. That's being said, as of now, we
have still the old scroll snap implementation, so the separation will introduce
complexity, the separation should be done once after the old implementation
removed.
There are 9 call sites of nsIPresShell::ScrollContentIntoView:
nsIPresShell::GoToAnchor
nsIPresShell::ScrollToAnchor
Element::ScrollIntoView
We definitely needs scroll-padding and scroll-margin for these functions.
nsCoreUtils::ScrollTo
This is used for Accesible::ScrollTo which scrolls to a given accesible node,
probably we should behave as what Element::ScrollIntoView does.
Accessible::DispatchClickEvent
Similar to the above, similated various mouse events on a given target node.
PresShell::EventHandler::PrepareToUseCaretPosition
PresShell::EventHandler::GetCurrentItemAndPositionForElement
Both are for context menu, we shouldn't consider scroll-padding and
scroll-margin.
nsFormFillController::SetPopupOpen
This is used for autocompletion popup, we shouldn't consider scroll-padding
and scroll-margin.
nsFocusManager::ScrollIntoView
This is bit unfortunate, we should use scroll-padding and scroll-margin
depending on call site of this function. Bug 1535232 is for this case.
cssom-view/scrollIntoView-scrollPadding.html which has some tests that is
actually testing scroll-padding with scrollIntoView passes with this change.
The reftest in this change is a test case that the browser navigates to an
element with specifying the anchor to the element.

When an SVG is used as a CSS background-image, we previously used the same behavior as
a normal image. It will stretch if the background-size is incompatible with the intrinsic
size of the SVG. This is a webcompat issue.
Now we use the painting destination rect size instead to avoid stretching.

Disable gtests observed to fail on Android. Some of these are simple build
failures and failures due to file permissions or paths, while other failures
are more obscure.
Once Android gtests are running on mozilla-central, I will file follow-up
bugs inviting teams to investigate the failures and re-enable Android gtests
that are important to them.
