Normally, assigning to e.g document.body.onload will forward to
window.onload. However, in a detached DOM tree, there is no associated
window, so we have nowhere to forward to, making this a no-op.
The bulk of this change is making Document::window() return a nullable
pointer, as documents created by DOMParser or DOMImplementation do not
have an associated window object, and so must be able to return null
from here.
That's not actually a DOM invariant, just something the HTML parser
refuses to build. You can still construct table-less th and td elements
using the DOM API.
If the provided ID is smaller than the corner clipping vector, we would
shrink the vector to match. This causes a crash when we have nested
PaintContext instances (as these IDs are allocated by PaintContext),
each of which perform radius painting.
This is seen on https://www.strava.com/login when it loads a reCAPTCHA.
The outer div has a border radius, which contains the reCAPTCHA in an
iframe. That iframe contains an SVG which also has a border radius.
Now, if an element belongs to a shadow tree, we use only the style
sheets from the corresponding shadow root during style computation,
instead of using all available style sheets as was the case
previously.
The only exception is the user agent style sheets, which are still
taken into account for all elements.

is affected because style of document no longer affects shadow tree
of input element, like it is supposed to be.

If a style element belongs to a shadow tree, its CSSStyleSheet is now
added to the corresponding ShadowRoot instead of the document.

This obviously excludes all shorthand properties. Eventually this test
should contain a property entry for all CSS value and animation types
(lengths, colors, custom animated properties, etc).
By storing a list of positioned and floating descendants within the
stacking context tree node, we can eliminate the need for costly
paintable tree traversals during hit-testing.
This optimization results in hit-testing being 2 to 2.5 times faster
on https://ziglang.org/documentation/master/
The specification says the final step of this algorithm is to return
null. Previously, the browser would crash if the content of an iframe
was appended to the document before its offsetParent property was
queried.
Previously @media rule conditions could be updated by assigning to
`conditionText`. This change aligns our implementation with the CSSOM
specification, which says `CSSConditionRule.conditionText` should be
read-only.
We had previous implemented some plumbing for file input elements in
commit 636602a54e.
This implements the return path for chromes to inform WebContent of the
file(s) the user selected. This patch includes a dummy implementation
for headless-browser to enable testing.
This reverts commit e52c30cbd5.
It's highly possible that this test was flaky on CI due to mixing units
of seconds and milliseconds in the transient activation calculation.
Revert the workaround for that commit in an attempt to avoid needless
ad-hoc behavior.
This commit fixes a regression introduced in
1528e9109c.
Turns out that the type of `this_value` in the property setter of the
Window object depends on how the variable is accessed. If the property
is accessed as a global variable, then this_value is of type `Window`.
For example:
```js
performance = null
```
However, when it is accessed as a property of the window object,
`this_value` is of type `WindowProxy`. For example:
```js
window.performance = null
```
This commit updates the window property setters generator to handle
both scenarios.
With this change https://discord.com/login works again.
This method asynchronously replaces the content of the given stylesheet
with the content passed to it.
An exception is thrown if this method is used by a stylesheet not
created with the `CSSStyleSheet()` constructor.
In particular, get the implicit root correctly for intersection
observers that don't have an explicit root specified.

Change `EventHandler::handle_keydown()` to no longer assume the cursor
position's node is always a `DOM::Text`. While this assumption holds
for `HTMLInputElement` that has a shadow DOM with a text node, an empty
`contenteditable` might not have any children. With this change,
`handle_keydown()` creates a new text node if the cursor position's
node is not a text node.
Setters for Window object should consider WindowProxy wrapper by:
- Verifying `this_value` is `WindowProxy` (not `HTML::Window`)
- Defining properties on the underlying Window object instead of on
the WindowProxy itself.
Transforms are applied to both clip rectangle and position, so we need
to remove the transform from clip rectangle before checking if position
falls within the clip rectangle.
In this change, the removal of transform is moved into
`Paintable::clip_rect()` that is shared between hit-testing and
painting.
This change fixes hit-testing in Discord's multifactor authentication
form.
If the layout has been recalculated and the sizes of scrollable
overflow rectangles could have changed, we need to ensure that scroll
offsets remain within the valid range.
By moving scroll offset clamp from `PaintableBox::scroll_by()` to
`PaintableBox::set_scroll_offset()`, we ensure that updates from
`Element::set_scroll_top()` and `Element::set_scroll_left()` are
constrained to a valid range.
