This fixes an issue where document.write() with only text input would
leave all the character data as unflushed text in the parser.
This fixes many of the WPT tests for document.write().
Instead of trying to locate the relevant StyleSheetList on style element
removal from the DOM, we now simply keep a pointer to the list instead.
This fixes an issue where using attachShadow() on an element that had
a declarative shadow DOM would cause any style elements present to use
the wrong StyleSheetList when removing themselves from the tree.
This is not that easy to use for test developers, as forgetting to set
the url back to its original state after testing your specific API will
cause future navigations to fail in inexplicable ways.
This patch implements `Range::getClientRects` and
`Range::getBoundingClientRect`. Since the rects returned by invoking
getClientRects can be accessed without adding them to the Selection,
`ViewportPaintable::recompute_selection_states` has been updated to
accept a Range as a parameter, rather than acquiring it through the
Document's Selection.
With this change, the following tests now pass:
- wpt[css/cssom-view/range-bounding-client-rect-with-nested-text.html]
- wpt[css/cssom-view/DOMRectList.html]
Note: The test
"css/cssom-view/range-bounding-client-rect-with-display-contents.html"
still fails due to an issue with Element::getClientRects, which will
be addressed in a future commit.
Attributes have a max value length of 1024. So we theoretically need to
support values in the range -${"9".repeat(1023)} to ${"9".repeat(1024)}.
These obviously do not fit in an i64, so we were previously failing to
parse the attribute.
We will now cap the parsed value to the numeric limits of an i64, after
ensuring that the attribute value is indeed a number.
Previously, attempting to get the computed value for a
grid-template-rows or grid-template-columns property would cause a crash
if the element had no associated paintable.
We currently implement the official cookie RFC, which was last updated
in 2011. Unfortunately, web reality conflicts with the RFC. For example,
all of the major browsers allow nameless cookies, which the RFC forbids.
There has since been draft versions of the RFC published to address such
issues. This patch implements the latest draft.
Major differences include:
* Allowing nameless or valueless (but not both) cookies
* Formal cookie length limits
* Formal same-site rules (not fully implemented here)
* More rules around cookie domains
This change ensures that the value sanitization algorithm is run and
the text cursor is set to the correct position when the type attribute
of an input is changed.
If grid-template-rows or grid-template-columns queried for a box that is
not a grid container, the result should be computed value instead of
null.
Fixes crashing in inspector.
Previously, there was a bug in the specification that would cause an
assertion failure, due to the abort event being fired before all
dependent signals were aborted.
That's awkward, but getComputedStyle needs to return used track values
for gridTemplateColumns and gridTemplateRows properties. This change
implements it by saving style values with used values into layout state,
so it could be assigned to paintables during LayoutState::commit() and
later accessed by style_value_for_property().
I haven't seen it used in the wild, but WPT grid tests extensively use
it. For example this change helps to go from 0/10 to 8/10 on this test:
https://wpt.live/css/css-grid/layout-algorithm/grid-fit-content-percentage.html
Instead of switching on the PropertyID and doing a boatload of
comparisons, we reorder the PropertyID enum so that all inherited
properties are in two contiguous ranges (one for shorthands,
one for longhands).
This replaces the switch statement with two simple range checks.
Note that the property order change is observable via
window.getComputedStyle(), but the order of those properties is
implementation defined anyway.

Before this change, we were cascading custom properties for each layer,
and then replacing any previously cascaded properties for the element
with only the set from this latest layer.
The patch fixes the issue by making each pass of the custom property
cascade add to the same set, and then finally assigning that set of
properties to the element.
This change adds green and red pass/fail emoji indicators to an in-tree
test — to make it easier to manually scan through the test results and
quickly see which cases are passing, and which are failing.
Depending on usage, `@layer` has two forms, with two different CSSOM
types. One simply lists layer names and the other defines a layer with
its contained rules.
Use offset from ScrollFrame which is an actual value a box is shifted by
while painting.
Also change `update_paint_and_hit_testing_properties_if_needed()` to
refresh scroll frames state, because `getBoundingClientRect()` now
depends on them.
Fixes wrong file tree sidebar location and excessive layout
invalidations caused by some miscalculation on JS-side when wrong
bounding client rect is provided on Github PR pages like

Otherwise, it looks a bit awkward where the cursor position does not
update while the selection is elsewhere.
Note that this requires passing along the raw selection positions from
`set the selection range` to the elements. Otherwise, consider what will
happen if we set the selection start and end to the same value. By going
through the API accessor, we hit the case where the start and end are
the same value, and return the document cursor position. This would mean
the cursor position would not be updated.
The test changes here more closely match what Firefox produces now. It
is not a 100% match; the `select event fired` test case isn't right. The
problem is the event fires for the input element, but we most recently
focused the textarea element. Thus, when we retrieve the selection from
the input element, we return the document's cursor position, which is
actually in the textarea element. The fix will ultimately be to fully
implement the following:
https://html.spec.whatwg.org/multipage/form-control-infrastructure.html#concept-textarea/input-cursor
That is, each input / textarea element should separately track its own
text cursor position.
In particular, there was an assertion failure due to the temporary
parser document's "about base URL" being empty when trying to "parse a
URL" during parsing.
We fix this by copying the context element's document's about base URL
to the temporary parsing document while parsing a fragment.

For both types of elements, `.selectionStart`, `.selectionEnd`,
`.selectionDirection`, `.setSelectionRange()`, `.select()` and the
`select` event are now implemented.
Before this change, :hover wouldn't match anything outside the shadow
boundary when hovering elements inside a shadow tree. This was most
noticeable when hovering the text inside an input element and hover
styles disappearing from the hosting input element itself.
