This change fixes accessible-name computation for:
- an element that has empty text content but that also has a title
attribute (“tooltip”) with a non-empty value
- an img element whose alt attribute is the empty string but that also
has a “title” attribute with a non-empty value
Otherwise, without this change, the accessible name unexpectedly isn’t
computed correctly for those cases.
A few are skipped for now:
- A few ref tests fail
- Crash tests are not supported by our runner and time out
- top-level-is-scope.html crashes and needs further investigation
If a rule gets its caches cleared because it's moved in the OM, then its
child rules' caches are likely invalid and need clearing too.
Assuming that caches only point "upwards", this will correctly clear
them all. For the time being that will be true.
We can't invalidate after the removal has taken effect, since that means
invalidation won't be able to find potentially affected siblings and
ancestors by traversing from the invalidation target.
This causes 36 new subtests to pass locally. :^)
Unfortunately at least one of these is flaky when it's able to load the
font file, apparently because we don't wait for the font and its
stylesheet to actually load before the tests run.
Eventually we want to stop skipping these, so it's helpful to know why
they were skipped in the first place. :^)
I've grouped them together by reason, so the order has changed a little.
For some of these the reason isn't clear.
Range API uses UTF-16 code units to represent offsets, so replace_data()
needs to use it instead of bytes count while calculating new offsets.
Fixes incorrectly thrown exception when non-latin string is passed into
replace_data().
This is enough for a basic shadow realm to work :^)
There is more that we still need to implement here such as module
loading and fixing up the global object, but this is enough to get some
basic usage working.
This object represents the global object for a shadow realm. The IDL
generator will need to be adjusted to the '[Global]' extended attribute
and no '[Exposed]' field (the change in the test is not correct, as I
understand it), but this should be enough to get us started on
shadow realms.
We were neglecting to check the namespace when looking for a specific
type of element on the stack of open elements in many cases.
This caused us to confuse HTML and SVG elements.
Element::tag_name() returns an uppercased string for HTML elements,
which is usually not what's expected by the parser algorithms that look
at tag names.
Letter spacing is applied during text shaping and `shape_text` is used
in places other `InlineLevelIterator` so way may have more work to do,
however this is a good start :^).
If the attribute value is the empty string `(lang="")`, the language
is set to unknown. `lang` attribute higher up in the document tree
will no longer be applied to the content of that element.
We guarded one step against a null navigable, but the very next step
also needs to be protected. Let's just abort early instead. This was
caught by the following imported WPT test:
html/dom/elements/the-innertext-and-outertext-properties/innertext-setter.html
This test adds a <frame> element and immediately removes it, but the
task to process the src attribute is already queued. Note that <iframe>
would have the same issue, but this test does not include them.
