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
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.
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.
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.
NavigableContainer is our home grown concept which already contains the
AOs needed for frame and iframe elements. This patch simply aligns our
HTMLFrameElement implementation with this class.
A couple of notes:
1. The <script> in the <head> element is intentional. The <frameset>
element effectively takes the place of the <body> element, and we
cannot add a <script> to a <frameset> element.
2. We don't render <frameset> or <frame> at all. Rendering is defined
in the following spec:
https://html.spec.whatwg.org/multipage/rendering.html#frames-and-framesets
3. If you load the test page in your browser, you won't see anything,
regardless of (2). Our test infra adds a <pre> element to the "body"
element (which is the <frameset> element here). Such children will
never be rendered. In the future, we could come up with something
better for our test infra to do, but this isn't important anyways
for this test - we can still grab the <pre> element's innerText.
This fixes structured serialization of DataView. It was expected
to be uniform with TypedArray, which returns u32 for byte_offset().
This was covered by a number of WPT infrastructure tests, which this
commit also imports.
Previously, callers were passing the size in bytes, but the method
expected bits. This caused a crash in LibCrypto when verifying the key
size later on.
Also make the naming of local variables and parameters a little more
clear between the different AES algorithms :^)
This change implements the “is a descendant of a native host language
text alternative element” condition in the “F: Name From Content” step
at https://w3c.github.io/accname/#step2F in the “Accessible Name and
Description Computation” spec — to ensure that all descendant nodes get
included as expected in computations for accessible names for elements.
Otherwise, without this change, Ladybird unexpectedly skips descendant
element nodes when computing accessible names — which can result in the
wrong accessible name being returned.
With a8077f79cc Selection object is no
longer aware of selection state inside text controls (<textarea> and
<input>), so this change makes them responsible for dispatching
`selectionchange` if their selection state was changed.
Stealing the callbacks from the AnimationFrameCallbackDriver made them
no longer safe from GC. Continue to store them on the class until we
have finished their execution.
Better support for CSS shorthands when setting the style attribute. This
improves some tests in WPT /css/css-align/default-alignment/*shorthand.
When setting the style attribute in JS via element.style = '..' or the
setAttribute method, shorthand properties were not expanded to longhand
properties.
The DOM spec gets overridden by both the SVG2 and MathML core specs in
that unknown elements should not inherit DOM::Element, but
SVG::SVGElement and MathML::MathMLElement respectively.
Previously, attempting to parse a floating point number with an integer
part larger than `(2 ^ 31) - 1` would cause the browser to crash. We now
avoid this by converting the integer part of the number to a `double`
rather than an `i32`.
This change imports the WPT accname/name/comp_embedded_control.html
test, along with related resources files it depends on.
Note that in the wai-aria/scripts/aria-utils.js file, this changes the
get_computed_label call to use our window.internals.getComputedLabel.
This seems to have vanished from the spec, but in any case, we still
need it. Without this change we erroneously thought that calculations
that match <percentage> did not match <number-percentage>.
This input event handling change is intended to address the following
design issues:
- Having `DOM::Position` is unnecessary complexity when `Selection`
exists because caret position could be described by the selection
object with a collapsed state. Before this change, we had to
synchronize those whenever one of them was modified, and there were
already bugs caused by that, i.e., caret position was not changed when
selection offset was modified from the JS side.
- Selection API exposes selection offset within `<textarea>` and
`<input>`, which is not supposed to happen. These objects should
manage their selection state by themselves and have selection offset
even when they are not displayed.
- `EventHandler` looks only at `DOM::Text` owned by `DOM::Position`
while doing text manipulations. It works fine for `<input>` and
`<textarea>`, but `contenteditable` needs to consider all text
descendant text nodes; i.e., if the cursor is moved outside of
`DOM::Text`, we need to look for an adjacent text node to move the
cursor there.
With this change, `EventHandler` no longer does direct manipulations on
caret position or text content, but instead delegates them to the active
`InputEventsTarget`, which could be either
`FormAssociatedTextControlElement` (for `<input>` and `<textarea>`) or
`EditingHostManager` (for `contenteditable`). The `Selection` object is
used to manage both selection and caret position for `contenteditable`,
and text control elements manage their own selection state that is not
exposed by Selection API.
This change improves text editing on Discord, as now we don't have to
refocus the `contenteditable` element after character input. The problem
was that selection manipulations from the JS side were not propagated
to `DOM::Position`.
I expect this change to make future correctness improvements for
`contenteditable` (and `designMode`) easier, as now it's decoupled from
`<input>` and `<textarea>` and separated from `EventHandler`, which is
quite a busy file.
We use the CSSRule::Type enum for identifying the type of a CSSRule, but
the spec requires that only some of these types are exposed via the
`type` attribute. For the rest, we're required to return 0, so let's do
so. :^)
The spec says that "isTrusted is a convenience that indicates whether
an event is dispatched by the user agent (as opposed to using
dispatchEvent())"
But when dispatching a pageshow event the flag was incorrectly set
to false.
