This ensures we cannot set or get cookies on non-HTTP(S) origins. Since
this would prevent our ability to test cookies during LibWeb tests, this
also adds an internals API to allow cookie access on file:// URLs.
With 6a549f6270 we need to check if
optional scrollable overflow exists for paintable box, because it's not
computed for inline nodes.
Fixes crashing after navigating into direct messages screen on Discord.
The reason we were keeping track of the pre-shaping buffer was to know
where we had tab characters in the input. This is a very strange way of
doing that, but since it broke the web, let's patch it up quickly.
Follow-up to #1870 which broke text layout on many web pages.
This fixes a browser crash as experienced on Wikipedia when encountering
the ≠ entity. As a side-effect, this also affects some tab-align and
-wrap tests.
Per css-ui-4, setting `appearance: none` is supposed to suppress the
creation of a native-looking widget for stuff like checkboxes, radio
buttons, etc.
This patch implements this behavior by simply falling back to creating
a layout node based on the CSS `display` property in such cases.
This fixes an issue on the hey.com imbox page where we were rendering
checkboxes on top of sender profile photos.
We only supported named properties on Storage, and as a result
`localStorage[0]` would be disconnected from the Storage's backing map.
Fixes at least 20 subtests in WPT in /webstorage.
These are created when a style rule has properties listed after another
rule. For example:
```css
.test {
--a: 1;
--b: 1;
--c: 1;
.thing {
/* ... */
}
/* These are after a rule (.thing) so they're wrapped in a
CSSNestedDeclarations: */
--d: 1;
--e: 1;
--f: 1;
}
```
They're treated like a nested style rule with the exact same selectors
as their containing style rule.
For example, this:
```css
.foo {
color: red;
&:hover {
color: green;
}
}
```
now has the same effect as this:
```css
.foo {
color: red;
}
.foo:hover {
color: green;
}
```
CSSStyleRule now has "absolutized selectors", which are its selectors
with any `&`s resolved. We use these instead of the "real" selectors
when matching them, meaning the style computer doesn't have to know or
care about where the selector appears in the CSS document.
We were hard-coding "about:blank" as the document URL for parsed HTML
documents, which was definitely not correct.
This fixes a bunch of WPT tests under /domparsing/ :^)
On any `display: list-item` Node a CSS pseudo element (`::marker`) needs
to be created. This commit allows the ::maker pseudo element to be
nested within other pseudo elements (e. g. ::before or ::after).
This fixes this WPT test:
http://wpt.live/css/CSS2/generated-content/after-content-display-003.xht
This resolves all WPT timeouts in html/canvas/element/manual/imagebitmap
We can now run an additional 6 tests and 126 subtests :)
This also adds regression tests for this behavior.
InlinePaintable was an ad-hoc paintable type required to support the
fragmentation of inline nodes across multiple lines. It existed because
there was no way to associate multiple paintables with a single layout
node. This resulted in a lot of duplicated code between PaintableBox and
InlinePaintable. For example, most of the CSS properties like
background, border, shadows, etc. and hit-testing are almost identical
for both of them. However, the code had to be duplicated to account for
the fact that InlinePaintable creates a box for each line. And we had
quite many places that operate on paintables with a code like:
```
if (box.is_paintable_box()) {
// do something
} else (box.is_inline_paintable()) {
// do exactly the same as for paintable box but using InlinePaintable
}
```
This change replaces the usage of `InlinePaintable` with
`PaintableWithLines` created for each line, which is now possible
because we support having multiple paintables per layout node. By doing
that, we remove lots of duplicated code and bring our implementation
closer to the spec.
Always create a new formatting context for <math> elements. Previously
that didn't happen if they only had inline children, e.g. mtable.
This fixes a crash in the WPT MathML test

Ignoring the fact that we should serialize a simplified form of calc()
expressions, the following are wrong:
- grid-auto-columns
- grid-auto-rows
- grid-template-columns
- grid-template-rows
- transform-origin
Generated in part with this python script (though I've since iterated on
the output repeatedly so it's quite different):
```py
import json
properties_file = open("./Userland/Libraries/LibWeb/CSS/Properties.json")
properties = json.load(properties_file)
for (key, value) in properties.items():
if not 'valid-types' in value:
continue
if 'longhands' in value:
continue
valid_types = value['valid-types']
for type_string in valid_types:
name, *suffix = type_string.split(None, 1)
match name:
case 'integer' | 'number':
print(f'{key}: calc(2 * var(--n));')
case 'angle':
print(f'{key}: calc(2deg * var(--n));')
case 'flex':
print(f'{key}: calc(2fr * var(--n));')
case 'frequency':
print(f'{key}: calc(2hz * var(--n));')
case 'length':
print(f'{key}: calc(2px * var(--n));')
case 'percentage':
print(f'{key}: calc(2% * var(--n));')
case 'resolution':
print(f'{key}: calc(2x * var(--n));')
case 'time':
print(f'{key}: calc(2s * var(--n));')
```
