In LayoutState, used_values_per_layout_node should not be modified in
order to determine inline nodes' dimensions - all the required values
should already be in there. In 2585f2da0d
we did accidentally create new values, causing the code further down to
try and get a PaintableBox from an anonymous container and crashing.
Fixes#6015.
Special handling for SVGClipPathElement and SVGMaskElement, which use a
a ViewBox and PreserveAspectRatio value internally, has been moved to
`SVGFormattingContext`.
If we were calculating the static position for an absolutely positioned
inline box that resides in the last line of its containing block, we
would not have yet provided the fragments in that line with their
final positions. Additionally, we would always move the box beneath the
fragment, which was incorrect.
Fixes#5867.
Currently we're relying on LineBuilder's destructor to handle updating
the last line, if required. In order to fix an issue with our absolute
positioning code, we need to be able to update the last line earlier
than that. Remove the destructor and replace it with an explicit call to
LineBuilder::update_last_line().
No functional changes.
One MessagePort can be entangled with another MessagePort, either in the
same agent, or in another agent.
In the same-agent case, the MessagePort objects point to each other via
the MessagePort::m_remote_port field.
In the separate-agent case, they live in separate processes entirely and
thus can't point at each other.
In both cases, the MessagePorts have an underlying transport channel,
which means they are "entangled". However, we can't assume that being
entangled means having a non-null m_remote_port.
This patch simply adds a missing null check for m_remote_port and thus
makes https://vscode.dev/ stop crashing with a null dereference.
This reverts e7890429aa and partly reverts
a59c15481f.
The one pseudo-class that accepted multiple of these was :heading(), and
since that got changed to take integers instead, there's no need to keep
this extra complexity (and memory usage) around.
We originally had special handling for `:host()` as that had been the
only pseudo-class that could be both an identifier or a function.
However, this meant duplicating the serialization logic, and also we
had to manually remember to add the same hack for any other
identifier-and-function cases. Which I forgot to do with `:heading()`!
So instead, for these cases, detect if they actually have arguments
specified and use that to determine which form to serialize as. We do
still have to write a check for each one of these pseudo-classes, but
the VERIFY should make it easier to remember.
We now also store `outline-width` in ComputedValues as a `CSSPixels`
since we know it's an absolute length at `apply_style` time - this saves
us some work in converting to CSSPixels during layout.
Gains us 46 new passes since we now interpolate keywords (thick, thin,
etc) correctly.
Also loses us 4 WPT tests as we longer clamp negative values produced by
interpolation from the point of view of getComputedStyle (although the
'used' value is still clamped).

`StyleValue`s stored within `ComputedProperties` should be in their
computed forms, this is for various reasons including:
- Inheritance should be of computed values
- Animations should work on computed values
- Triggering transitions should work on computed values
Currently we store `StyleValue`s in an absolutized version of the
specified value - this is equivalent to the computed form in many cases
which is why this hasn't been causing significant issues but there are
some cases - such as `border-*-width` keywords where this is not the
case.
No functionality change as we are yet to implement any properties
This removes the AnimationRefresh argument from `collect_animation_into`
which was added in a9b8840 - it's only effect was disallowing
`UseInitial`s within keyframes when we were doing animated style
updates which I believe is unintentional.
Gains us 214 WPT tests.
