We're still missing the lazy loading attribute handling, and once we hit
the navigation step, we fall back to totally ad-hoc behavior instead of
going all the way with a Fetch Request.
We had glossed over a condition in the spec that said we should only run
the nested context creation steps when the iframe's own containing
document has a browsing context.
We already had a helper for this, but compute_height() wasn't using it.
Tweak it so that compute_height() can use it, and remove the duplicated
code that's now redundant.
This remained undetected for a long time as HeaderCheck is disabled by
default. This commit makes the following file compile again:
// file: compile_me.cpp
#include <LibWeb/HTML/CrossOrigin/CrossOriginOpenerPolicy.h>
// That's it, this was enough to cause a compilation error.
Likewise for most other files touched by this commit.
The flex line cross size includes the margin boxes of items, so when
we're taking the flex line's cross size to use as an item cross size,
we have to subtract the margin, border padding from both sides.
Previous we only subtracted the cross margins, which led to oversized
items in some cases.
It's not safe to capture `this` as a raw pointer here, since nothing
is guaranteed to keep the ResourceClient alive (even if the Resource
stays alive.)
Instead of creating a new HTMLCollection every time you access
.children, we now follow the spec and vend the same object.
This was annoyingly difficult before, and trivial now that the DOM is
garbage-collected. :^)
Instead of asking Gfx::FontDatabase for the "default font" and the
"default fixed-width font", we now proxy those requests out via
the Platform::FontPlugin. This will allow Ladybird to use other default
fonts as fallback.
Propagate errors in places that are already set up to handle them, like
WebGLRenderingContext and the Tubes demo, and convert other callers
to using MUST.
This replaces the previous Web::ImageDecoding::Decoder interface.
While we're doing this, also move the SerenityOS implementation of this
interface from LibWebView to WebContent. That means we no longer have to
link with LibImageDecoderClient in applications that use a web view.
This patch combines a number of techniques to make inline content flow
more correctly around floats:
- During inline layout, BFC now lets LineBuilder decide the Y coordinate
when inserting a new float. LineBuilder has more information about the
currently accumulated line, and can make better breaking decisions.
- When inserting a float on one side, and the top of the newly inserted
float is below the bottommost float on the opposite side, we now reset
the opposite side back to the start of that edge. This improves
breaking behavior between opposite-side floats.
- After inserting a float during inline layout, we now recalculate the
available space on the line, but don't adjust X offsets of already
existing fragments. This is handled by update_last_line() anyway,
so it was pointless busywork.
- When measuring whether a line can fit at a given Y coordinate, we now
consider both the top and bottom Y values of the line. This fixes an
issue where the bottom part of a line would bleed over other content
(since we had only checked that the top Y coordinate of that line
would fit.)
There are some pretty brain-dead algorithms in here that we need to make
smarter, but I didn't want to complicate this any further so I've left
FIXMEs about them instead.
This implements all the filters other than `saturate()`,
`hue-rotate()`, and `drop-shadow()`.
There are still a lot of FIXMEs to handle in the actual implementation
though, particularly around supporting transforms, but this handles
the most common use cases :^)
This style value holds a list of CSS filter function calls e.g.
blur(10px) invert() grayscale()
It will be used to implement backdrop-filter, but the same style value
can be used for the image filter property.
(The name is a little awkward but it's referenced to as
filter-value-list in the spec too).
When matching selectors in HTML documents, we know that all the elements
have lowercase local names already (the parser makes sure of this.)
Style sheets still need to remember the original name strings, in case
we want to match against non-HTML content like XML/SVG. To make the
common HTML case faster, we now cache a lowercase version of the name
with each type/class/id SimpleSelector.
This makes tag type checks O(1) instead of O(n).
This remained undetected for a long time as HeaderCheck is disabled by

// That's it, this was enough to cause a compilation error.
The document.domain setter is currently stubbed as that is a doozy to
implement, given how much restrictions there are in place to try and
prevent use of it and potential multi-process implications.
