Contradictory to the spec, the Set Timeouts endpoint should update the
existing timeouts configuration in-place, rather than replacing it. WPT
expects this, and other browsers already implement this endpoint this
way.
This is a method defined in the WebDriver spec, but requires access to a
bunch of private fields in these classes, so this is implemented in the
same manner as the reset algorithm.
The "isCollapsed" attribute on a selection must "return true if and only
if the anchor and focus are the same".
In addition to checking that the anchor and focus belonged to the same
DOM node, we now also check that they refer to the same position within
the node.
With this change Ladybird passes all the subtests in the "isCollapsed"
WPT suite.

This way we don't have to allocate separate vector with both scroll and
sticky frame that is used for display list player (scroll and sticky
frames share id pool), so player could access offset by frame id.
No behavior change.
...and add display list item that does translation instead. By doing
that we no longer need to map each coordinate in display list by
translation in recorder state.
Printing the whole array causes wpt
console/console-log-large-array.any.html to crash.
This limits logged arrays to 100 elements and
truncates the rest with ...
- Add support for placement of abspos items into track formed by last
line and padding edge of grid container
- Correctly handle auto-positioned abspos items by placing them between
padding edges of grid container
Fixes crashing on https://wpt.live/css/css-grid/abspos/positioned-grid-descendants-001.html
We have support for using (shift+)tab to move focus to the next/previous
element on the page. However, there were several ways for this to crash
as written. This updates our implementation to check if we did not find
a node to move focus to, and to reset focus to the first/last node in
the document.
This doesn't seem to work when wrapping around from the first to the
last node. A FIXME has been added for that, as this would already not
work before this patch (the main focus here is not crashing).
This is necessary when we add more ServiceWorker capabilities, that
actually check this value. The more this spoof functionality is used,
the more we'll need to actually support serving test files over https.
Our handling of left vs. right modifiers keys (shift, ctrl, etc.) was
largely not to spec. This patch adds explicit UIEvents::KeyCode values
for these keys, and updates the UI to match native key events to these
keys (as best as we are able).
...traversal. We've already fixed step 3 and 9 to not filter out
non-positioned stacking contexts, because modern CSS has more ways to
create stacking context besides being positioned with z-index (like by
using "transform", "filter" or "clip-path" properties).

Prior to this change, SVGs were following the CSS painting order, which
means SVG boxes could have established stacking context and be sorted by
z-index. There is a section in the spec that defines what kind of SVG
boxes should create a stacking context
https://www.w3.org/TR/SVG2/render.html#EstablishingStackingContex
Although this spec is marked as a draft and rendering order described in
this spec does not match what other engines do.
This spec issue comment has a good summary of what other engines
actually do regarding painting order
https://github.com/w3c/svgwg/issues/264#issuecomment-246432360
"as long as you're relying solely on the default z-index (which SVG1
does, by definition), nothing ever changes order when you apply
opacity/filter/etc".
This change aligns our implementation with other engines by forbidding
SVGs to create a formatting context and painting them in order they are
defined in tree tree.
When the TokenStream code was originally written, there was no such
concept in the CSS Syntax spec. But since then, it's been officially
added, (https://drafts.csswg.org/css-syntax/#css-token-stream) and the
parsing algorithms are described in terms of it. This patch brings our
implementation in line with the spec. A few deprecated TokenStream
methods are left around until their users are also updated to match the
newer spec.
There are a few differences:
- They name things differently. The main confusing one is we had
`next_token()` which consumed a token and returned it, but the spec
has a `next_token()` which peeks the next token. The spec names are
honestly better than what I'd come up with. (`discard_a_token()` is a
nice addition too!)
- We used to store the index of the token that was just consumed, and
they instead store the index of the token that will be consumed next.
This is a perfect breeding ground for off-by-one errors, so I've
finally added a test suite for TokenStream itself.
- We use a transaction system for rewinding, and the spec uses a stack
of "marks", which can be manually rewound to. These should be able to
coexist as long as we stick with marks in the parser spec algorithms,
and stick with transactions elsewhere.
