A previous commit made it so that SeekTable doesn't provide a seek
point from `seek_point_before()` if there is not a seek point before
the requested sample index. However, MP3Loader was only setting a seek
point after the first 10 frames, meaning that it would do nothing when
seeking back to 0.
To fix this, add a seek point at byte 0 for the first sample, so that
`seek_point_before()` will never fail.
Instead, perform the filtering for each rule as we go. This avoids
creating a separate list of rules, which was ~5% of runtime when
mousing around on the Discord web interface.
This patch implements "Overflow Viewport Propagation" from CSS-OVERFLOW.
It fixes an issue where many websites were not scrollable because they
had `overflow: scroll` on the body element and we didn't propagate it.
This is based on Jakt::File::current_executable_path() and all the other
sources I looked at to figure out the per-platform way to do this. My
goodness, every platform has its own bespoke way.
...along with `outline-color`, `outline-style`, and `outline-width`.
This re-uses the existing border-painting code, which seems to work well
enough!
This replaces the previous code for drawing focus-outlines, with generic
outline painting for any elements that want it. Focus outlines are now
instead supported by this code in Default.css:
```css
:focus-visible {
outline: auto;
}
```
Don't give up if we can't parse that single value for the property
directly, but let the parsing code carry on and see if we can produce a
CompositeStyleValue.
This fixes an issue with some typefaces where the space character has an
advance width, but no glyf entry (and thus no ascent/descent). Before
this change, we'd render whitespace with zero advance in such cases.
I'm not sure if this is exactly correct, the link to CSS2 spec above
says something that clearance cannot separate boxes, but I'm not sure if
I understood it correctly or if I've done it in the right place.
However, this change fixes our block-and-inline/clearfix.html test again
(was regressed in previous commit).
Pseudo-elements like ::before and ::after were discarded when their
content property was an empty string (ignoring whitespace), because they
are anonymous containers with no lines.
Our previous way around it was to add an empty line box (see b062a0fb7c)
however it didn't actually work for cases described in the previous
commit.
This makes avatars and cover arts square on last.fm and "fixes" the test
css-pseudo-element-should-not-be-affected-by-presentational-hints.html.
Unfortunately, this also regresses on block-and-inline/clearfix.html,
but that hopefully will be handled in subsequent commit.
This reverts commit b062a0fb7c.
This made a calculation of pseudo-elements' height incorrect when they
had `height` set to `auto` and used other techniques (like setting
`padding-top`) to set height, as it was now also adding an empty line.
Additionally, the case didn't work for content containing whitespace
characters, so a pseudo-element with `content: " "` didn't have *this*
particular problem.
This patch adds handling of the 'object-fit' CSS property to the
painting of HTML Image Elements.
This is achieved by first calculating the rect which the image would
need if it were to fully expand into open space and then adequately
cropping it to fit into the image's box.
scale-down is not supported for now.
LibTLS still can't access many parts of the web, so let's hide this
behind a flag (with all the plumbing that entails).
Hopefully this can encourage folks to improve LibTLS's algorithm support
:^).
Re-organize our helper files here a bit, to make a clearer distinction
between Qt-specific helpers and generic non-serenity helpers.
A future commit will move Lagom specific code from LibSQL to ladybird
as well, so that we can see about future generic apis for spawning
helper procesess.
This fixes the "last changed" time for files on GitHub. Note that this
appears to be in accordance with the shadow DOM specification, but I
can't find a line that neatly says it. Though on Google's post about
shadow DOM v1 it says:
> "the element's shadow DOM is rendered in place of its children."

The Blob URL store is intended to be a singleton across all WebContent
instances. But for now, this implements a per-WebContent store, which
only lives as long as the WebContent process itself.
This adds a simple and incomplete implementation for extracting some
specific CORS headers that are used by fetch. This unifies the existing
ad-hoc parsing that already existed for Access-Control-Allow-Headers
and Access-Control-Allow-Methods, as well as adding
Access-control-Expose-Headers.
This adds the headers named in Access-Control-Expose-Headers to the
response's CORS-exposed header-name list which allows those headers to
be accessed from JS.
Properties like min-width, max-width, etc, should be ignored while we're
trying to determine the intrinsic size of a flex container.
This fixes an infinite recursion when using an intrinsic size keyword as
the max-width of a flex column container.
Note that this behavior is marked as AD-HOC in code comments because
specs don't tell us how to achieve intrinsic sizing.
We can now load product pages on the Twinings site, such as
https://twinings.co.uk/products/earl-grey-100-tea-bags :^)
Otherwise, in a simple page such as:
<video src=...>
<audio src=...>
The video's clip rect would "leak" to the AudioPaintable, preventing the
audio controls from rendering at all.
