Introduce has_ongoing_navigation() that allows to check if resource
state in FrameLoading is pending. This API is going to be used in
upcoming fix for wait_for_navigation_to_complete() in WebDriver.
Before execute_async_script supported returning value from script to
/execute/async caller only if script returns promise that resolves into
returned value. This change fixes execute_async_script to also support
returning value to caller using callback that is always passed to
script as a last argument.
Previously this was compiled to require an object despite the IDL file
specifying 'optional'.
This commit makes IDLGenerator respect this modifier, and fixes the only
affected instance.
Separating the paths for replaced and non-replaced floating boxes lost
the logic for margin, padding and border which was done by
compute_width_for_floating_box. Set them the same way as we do for
block-level replaced elements, per the specification.
Since there are no table-specific boxes anymore it would be nice to
output their types additionally in layout dump so we can tell table
boxes from "regular" boxes.
Now that the processResponseConsumeBody algorithm receives the internal
response body of the fetched object, we do not need to go out of our way
to read its body from outside of fetch.
However, several elements do still need to manually inspect the internal
response for other data, such as response headers and status. Note that
HTMLScriptElement already does the new workaround as a proper spec step.
Solves conflict in layout tree "type system" when elements <label> (or
<button>) can't have `display: table` because Box can't be
Layout::Label (or Layout::ButtonBox) and Layout::TableBox at the same
time.
Unlike DOM mutations, CSS animations don't affect the style of the
entire subtree of the element being animated. This means we only have to
recompute style for the animating element, which is significantly
faster than doing the whole subtree.
This takes idle CPU usage on https://shopify.com/ from 100% to 30% on my
(not massively powerful) laptop. :^)
This commit makes the StyleComputer avoid restarting finished animations
(e.g. animations with finite iteration counts that have run to
completion).
As a bonus, it also disables the animation timer when all animations
have finished running.
This partially implements CSS-Animations-1 (though there are references
to CSS-Animations-2).
Current limitations:
- Multi-selector keyframes are not supported.
- Most animation properties are ignored.
- Timing functions are not applied.
- Non-absolute values are not interpolated unless the target is also of
the same non-absolute type (e.g. 10% -> 25%, but not 10% -> 20px).
- The JavaScript interface is left as an exercise for the next poor soul
looking at this code.
With those said, this commit implements:
- Interpolation for most common types
- Proper keyframe resolution (including the synthetic from-keyframe
containing the initial state)
- Properly driven animations, and proper style invalidation

This allows us to figure out where a specific CSS property comes from,
which is going to be used in a future commit to uniquely identify
running animations.
The comment mentions that zero is let through, but then immediately
errors out if it sees any number outside quirks mode.
This commit makes that check let zeros through.
From spec https://drafts.csswg.org/css-grid/#grid-items:
"Each in-flow child of a grid container becomes a grid item, and each
child text sequence is wrapped in an anonymous block container grid
item."
Fixes the problem that text sequences inside grid containers are
ignored and not displayed.
Fixes the bug that currently we always consider tracks with percentage
size as ones with "fixed" length even when available size is not
definite. With this change tracks with percentage size when available
size is not definite will be considered as "intrinsic" sized.
We were not taking reverse flex directions into account when choosing
the initial offset for flex item placement if justify-content were
either space-around or space-between.
We have to check that the entry in CrossOriginProperties is the one
actually requested from the caller before executing the body of the
loop. This fixes a crash triggered by YouTube iframe embedding.
Instead of eagerly populating the stack trace with a textual
representation of every call frame, just store the raw source code range
(code, start offset, end offset). From that, we can generate the full
rich backtrace when requested, and save ourselves the trouble otherwise.
This makes test-wasm take ~7 seconds on my machine instead of ~60. :^)
This PR corrects the signs of the start/end points that are passed
to the elliptical_arc_to(), it also removes the bogus path.close()
after creating the arc. Now .arc() seems to work correctly.
...and use it for `margin` and `padding`.
So now, if all four margins are 12px, we output "12px" instead of "12px
12px 12px 12px". This matches the spec's requirement to use the smallest
non-ambiguous representation.
Previously, this would blindly use parse_number() without checking if
there was a number to parse. This meant we would crash on transforms
like:
rotate(BAD 32 0)
Now the attribute just gracefully fails to parse.
BrowsingContext::set_active_document() may end up asking for the Page's
top level browsing context before Page has one. Do a workaround for now
where we have an API to ask if it's initialized.
Long-term we should find a cleaner solution.
