This commit introduces a new preference option
mathml.nonzero_unitless_lengths.disabled to disable MathML nonzero unitless
values like "5" for 500%. MathML nonzero unitless are now disabled by default
but it could be easily enabled again later if we decide otherwise.
* test_bug553917.html is updated to check that these values now cause an error
message to be logged into the console rather than a deprecated warning
when nonzero unitless lengths are disabled.
Additionally, the test checking invalid double dots "2..0" is updated not
to use unitless syntax.
* The old test 355548-3.xml checks support for mathsize names and also uses
several features that are going to be deprecated. So it is just run with
the proper preference adjustment.
* mfrac-linethickness-2.xhtml and number-size-1.xhtml check support for
unitless lengths so they are now run with that support enabled.
* WPT tests frac-linethickness-001.html and lengths-1.html are executed with
the some MathML features disabled in order to make them pass.
We get more assertion passing for the "Legacy numbers" test of
lengths-2.html ; however there are still some issues to address
(see bug 1574751).

This commit introduces a new preference option
mathml.mathsize_names.disabled to disable mathsize keyword values. For
now, these are only disabled in Nightly builds.
* test_bug553917.html is updated to check that these values now cause an
error message to be logged into the console when mathsize names are used
and the feature disabled.
* The old test 355548-3.xml checks support for mathsize names and also uses
several features that are going to be deprecated. So it is just run with
the proper preference adjustment.
* mathml/relations/css-styling/mathsize-attribute-legacy-values.html passes
after this change so the test is run with the mathsize names disabled too
and the failure expectation is removed.
* mathml/relations/css-styling/mathsize-attribute-css-keywords.html is added
to check that CSS keywords won't be supported when we switch to using the
CSS parser in the future. This test passes now when the "small" keyword
is not accepted so it is run with the mathsize names disabled too.

This condition was needed when FindInsertionPrevSibling and co didn't understand
display: contents.
Editor is pretty broken (and calls into PresShell::ContentRemoved directly, and
incorrectly, using anonymous nodes).
In this case we were taking the XBL path because of display: contents, which
means that we tried to seek to the editor anonymous node, and crash (since it's
not an explicit kid).
Editor needs to get fixed, but this is technically more correct and fixes the
crash, so we may as well take it in the interim.

Update test_bug553917 so that it does not expect invalid lengths
for "thin", "thick", "medium" when mfrac linethickness names are
allowed. This fixes failure in non-nightly builds where these
names are not disabled yet.

When contents notify IME or requests something to IME, they need to use
an `nsIWidget` instance which may have focus if active, and handles
native keyboard/IME events since that knows correct native IME context.
Currently, such widget exactly matches with the result of
`nsPresContext::GetRootWidget()`. However, this is unclear for most developers.
Therefore, this patch creates a wrapper method of it named
`nsPresContext::GetTextInputHandlingWidget()`. Then, also adds
`BrowserParent::GetTextInputHandlingWidget()` wraps it. Finally, makes
`IMEStateManager` call `GetTextInputHandlingWidget()` of them.

This commit introduces a new preference option
mathml.mfrac_linethickness_names.disabled to disable linethickness names. For
now, these names are only disabled in Nightly builds. Announcements and actual
disabling of this and other MathML features will be considered later.
* test_bug553917.html is updated to check that these values now cause an error
message to be logged into the console.
* mstyle-1.xhtml is updated to use a numeric linethickness since the point of
the test is just to check that the attribute is not supported on mstyle, not
about the actual attribute value.
* Other fractions tests relying on linethickness names are executed with the
proper preference adjustment.
* mathml/presentation-markup/fractions/frac-linethickness-001.html is now
closer to its expectation ; however the test still fails because nonzero
unitless values are not removed yet. See

Resolution is at:
* https://github.com/w3c/csswg-drafts/issues/3779#issuecomment-481762912
Tests are at https://chromium-review.googlesource.com/c/chromium/src/+/1547974,
I'll make sure to wait until they're in the tree and ensure they're passing.
Note that we need to ensure in the frame constructor that the document element
is styled _before_ calling UpdateViewportScrollStylesOverride(). This saves
duplicated work (since ResolveStyleLazily throws away the style).
ResolveStyleLazily already returns out of date styles, unless the element is not
styled yet, or is in a `display: none` subtree, in which case it computes and
returns a new (up-to-date) style.
So the switch to the FFI call only should change behavior for the display: none
subtree case (since we ensure the unstyled case isn't hit by styling the
document earlier). But that case is one of the cases we're interested in
changing, conveniently.
Depends on D40080

Return a raw pointer instead of a strong reference to a ComputedStyle, and
handle the case of the style not being present by returning null rather than
requiring an extra function to check it and crashing if the precondition is not
met.
Also, name them so that it's clear they just return outdated styles and don't
make any extra effort.
This is just cleanup that makes the next patch easier / more obvious.

This is mostly straight-forward cleanup, but there's a behavior change which
was an oversight from bug 1386840, the regular mObservers stuff didn't pass the
right thing (was passing only mWasAlternate rather than whether it was
deferred).
I think that as a result, only in XML documents (since nsXMLContentSink is the
only thing that adds itself as a global CSS loader observer that ever looks at
this boolean), we may end up breaking this assert:
https://searchfox.org/mozilla-central/rev/9ae20497229225cb3fa729a787791f424ff8087b/dom/base/nsContentSink.cpp#183
(If there are any sheets with non-matching media queries and such).
But I couldn't find a test-case that broke it (tried SVG / XHTML), and in other
documents like pure XML you cannot specify a media query...

Saving a refcount bump is not worth the churn. Use a proper RefPtr<>
everywhere instead of manual refcounting, and don't make DoSheetComplete call
NS_RELEASE unconditionally.
Also, make clear by using references where null is expected or not.
Also, properly use a RefPtr in mPendingDatas, since they are strong pointers,
in fact.
Finally, remove some unused macros from nsCSSValue of which this code was the
last consumer.

The current code needs to handle incomplete draws already due to async decoding,
and this prevents the race condition where we paint between the size-available
and load notifications, as the CSS image loader only invalidates for the first.
Once we try to decode the image at least once, then we'd repaint properly from
ImageLoader::OnFrameComplete.

So the issue here is that this test-case has a zero-sized border, but still with
a border-image (which we should paint).
So the first time we get here, the image is not loaded, and thus we don't get
here:
https://searchfox.org/mozilla-central/rev/e0b0c38ee83f99d3cf868bad525ace4a395039f1/layout/painting/nsDisplayList.h#4254
Which means that we end up with zero bounds and thus we don't even get to the
border painting code.
However, when the image loads, we get to MarkNeedsDisplayItemRebuild(), but that
doesn't schedule any paint, only marks the frames as modified in order for
display items to be rebuilt _eventually_.
Thus eventually, where we force a repaint by other means, we paint correctly.
This only works in more general cases because we get to the nsImageRenderer code
which does vastly different stuff.
InvalidateFrame() seems to do the right thing and schedule a paint, so use it.
It's not clear to me which one of nsIFrame::InvalidateFrame() or
nsIFrame::SchedulePaint() we should use...
If I understand correctly, InvalidateFrame() will only do something iff there
are display items for the frame, so that should make the IsVisible() check
redundant.
Note however that I think there's still a race condition, if we get to paint in
between the SIZE_AVAILABLE notification (the one where we actually invalidate
the display items), and the LOAD notification (the one the border-image code
checks).
I'll send a separate patch for that, I think SIZE_AVAILABLE should be a
strong-enough hint and that allows us to remove nsStyleImage::IsLoaded()...
The RequestReflow stuff also looks highly suspicious... shape-outside
sync-decodes, and it seems we could end up invalidating reflow from the reflow
code...

We always pass consumed block-size into BlockReflowInput's constructor
