This change adds support for computing accessible names for SVG
elements, per the https://w3c.github.io/svg-aam/#mapping_additional_nd
spec requirements. Otherwise, without this change, accessible names for
SVG elements don’t get exposed as expected.
Also removing a FIXME about not covering all of the event names as it is
not exactly clear when such a FIXME would be addressed, especially as
these come from multiple specifications.
- Hue now wraps properly when negative or larger than 360
- The hsl to rgb conversion now closely mirrors the code example from
the spec.
This fixes a number of WPT tests in
/css/css-color/parsing/color-computed-hsl.html
We now have the Temporal facilities to implement the Date AOs which
parse UTC offset strings using the ISO8601 parser. This patch updates
those AOs and their callers in accordance with the Temporal spec.
This started with implementing TemporalMonthDayString. It turns out that
the facilities needed to parse that production includes nearly all the
helpers to parse each of:
TemporalDateTimeString
TemporalInstantString
TemporalMonthDayString
TemporalTimeString
TemporalYearMonthString
TemporalZonedDateTimeString
As most of these invoke the same helpers with different options. So,
all 6 of those productions are implemented here.
Now, along with the mouse events we also dispatch pointerup, pointerdown
and pointermove.
With this change shape painting works on https://excalidraw.com/
Previously, the list was copied when constructing the FormData object,
then the original list was passed to the event, meaning any changes to
the list that happened within the event would not be reflected outside
of it.
This commit introduces proper handling of three intrinsic size keywords
when used for CSS heights:
- min-content
- max-content
- fit-content
This necessitated a few plumbing changes, since we can't resolve these
values without having access to containing block widths.
This fixes some visual glitches on https://www.supabase.com/ as well
as a number of WPT tests. It also improves the appearance of dialogs.
An inopportune garbage collection may cause collected `ResizeObserver`s
to unregister themselves from `m_resize_observers` while we are
iterating over it, resulting in a use-after-free.
For example, in the following HTML:
```html
<label>
<input type="radio" name="fruit" value="apple" id="radio1">
<span class="box"></span>
</label>
```
When any descendant of a <label> element is clicked, a "click" event
must be dispatched on the <input> element nested within the <label>, in
addition to the "click" event dispatched on the clicked descendant.
Previously, this behavior was implemented only for text node descendants
by "overriding" the mouse event target using `mouse_event_target()` in
the TextPaintable. This approach was incorrect because it was limited to
text nodes, whereas the behavior should apply to any box. Moreover, the
"click" event for the input control must be dispatched *in addition* to
the event on the clicked element, rather than redirecting it.
