The `muted` content attribute should only affect the state of the
`muted` IDL property when the media element is first created. The
attribute should have no dynamic effect.
Opaque origins are meant to be unique in terms of equality from
one another. Since this uniqueness needs to be across processes,
use a nonce to implement the uniqueness check.
Documents created via DOMParser.parseFromString()
are parsed synchronously and do not participate in the
browsing context's loading pipeline.
This patch ensures that if the document has no browsing context
(i.e. was parsed via DOMParser),
its readiness is set to "complete" synchronously.
Fixes WPT:
domparsing/xmldomparser.html
Fix various TODO by checking the validity of ECDSA and ECDH keys when
they are imported. There are no checks in place for raw import because
the spec doesn't contemplate them yet.
Also add some internal tests since WPT doesn't seem to provide them.
Previusly the implementation only was serializing PseudoElements if they
were the last element in the CompoundSelector. This caused bugs on
Javascript code that referenced their selectorText, where it would be
wrong.
Documents created by DOMParser and fragment documents do not
have an origin set on the document by the spec. These documents
also happen to never become fully active.
By properly implementing the steps for the <img> element to only
update the image data for documents which are fully active, this
fixes a crash for img elements in these types of documents.
Unfortunately, this is not a full fix for the microtask queue case.
This is because it seems possible for node document for an <img>
element to be changed during the microtask queue for that document.
It is not clear to me how this can be fixed in a nice way.
Previously we would incorrectly map these in
`CSSStyleProperties::convert_declarations_to_specified_order`, aside
from being too early (as it meant we didn't maintain them as distinct
from their physical counterparts in CSSStyleProperties), this meant
that we didn't yet have the required context to map them correctly.
We now map them as part of the cascade process. To compute the mapping
context we do a cascade without mapping, and extract the relevant
properties (writing-direction and direction).
As conflict resolution depends on whether the property was set directly
or via a shorthand, we have to store the non-expanded values in the
resolved keyframe properties.
When we try to insert a disallowed (non-nested) statement into a
CSSGroupingRule we should throw a `HierarchyRequestError` as it being
disallowed is a "constraint specified by CSS". Previously we would rely
on `Parser::is_valid_in_the_current_context` and throw a Syntax error.
There are more constraints to be implemented.
This commit implements the fallback to the documents fallback base url
if the href of the first base element is a data or javascript url.
Additionally the frozen base url is set, if a base element becomes the
first base element with an href content attribute because the previous
one got removed.
`collapse_auto_fit_tracks_if_needed()` had a check that does collapsing
only if auto-fit is used like
`grid-template-columns: repeat(auto-fit, 1px);`, and it didn't work for
valid cases when `repeat(auto-fit)` is placed in the middle of
definition like `grid-template-columns: 1px repeat(auto-fit, 1px) 1px;`.
`getComputedStyle()` for grid tracks returns style value produced during
layout. This is needed to return resolved track sizes values which are
thrown away after layout is done. Now GFC produces more correct style
value by not ignoring grid line names.
Reimplements `grid`, `grid-template`, `grid-template-rows`, and
`grid-template-columns` in a way that uses a separate function for each
grammar rule defined in the specification. This change results in many
additional passing tests from the already imported WPT suite. Most of
the remaining test failures are related to incorrect serialization of
grid properties.
In `InlineLevelIterator`, whenever we call `skip_to_next()` and enter a
node with box model metrics, we could potentially accumulate leading and
trailing metrics. This lead to a weird situation where an element with
`display: inline-block` could adopt the leading metrics of an inline
element that follows it, since we perform the call to
`add_extra_box_model_metrics_to_item()` too late.
Move `skip_to_next()` down so it no longer interferes with the `Item`
we're creating.
The test expectation for
`atomic-inline-with-percentage-vertical-align.html` is updated, although
neither the old nor new results are 100% accurate since either box jumps
one pixel to the right.
There are multiple things happening here which are interconnected:
- We now use AbstractElement to refer to the source of a counter, which
means we also need to pass that around to compute `content`.
- Give AbstractElement new helper methods that are needed by
CountersSet, so it doesn't have to care whether it's dealing with a
true Element or PseudoElement.
- The CountersSet algorithms now walk the layout tree instead of DOM
tree, so TreeBuilder needs to wait until the layout node exists
before it resolves counters for it.
- Resolve counters when creating a pseudo-element's layout node. We
awkwardly compute the `content` value up to twice: Once to figure out
what kind of node we need to make, and then if it's a string, we do
so again after counters are resolved so we can get the true value of
any `counter()` functions. This will need adjusting in the future but
it works for now.
