Serenity handles this in the SystemServer already, but the simplest
place to put this logic is the ViewImplementation base class.
This is trivial to see when running Ladybird without SERENTIY_SOURCE_DIR
set, or set improperly.
This closely mirrors Socket::set_blocking. Note that it does not make
sense to make this a virtual method on a base class, since
SeekableStream and FixedMemoryStream cannot possible be anything except
than blocking.
Previously, this would blindly use parse_number() without checking if
there was a number to parse. This meant we would crash on transforms
like:
rotate(BAD 32 0)
Now the attribute just gracefully fails to parse.
BrowsingContext::set_active_document() may end up asking for the Page's
top level browsing context before Page has one. Do a workaround for now
where we have an API to ask if it's initialized.
Long-term we should find a cleaner solution.
This fixes an issue where loading an iframe would cause the current
browser tab title to get overwritten with an empty string.
The problem is that nested browsing contexts can be considered "top
level" during their initialization, but only one browsing context is
ever the Page::top_level_browsing_context(), so that's what we check.
Although we translate e.g `block` to `block flow` for internal use in
the engine, CSS-DISPLAY-3 tells us to use the short form in
serializations for compatibility reasons.
This adds 9 points to our score on https://html5test.com/ :^)
This will contain several of the fixed data tables from the VP8 spec.
For starters, it contains the tables needed to read the frame header
in the first partition. These tables are needed to read the
probabilities of the metablock predicition modes, which in turn will
be needed to read the metablock predicition modes themselves.
Specifically, stop letting NumericStyleValues holding `0` from
pretending to hold a Length. The parser is now smart enough that we
don't have to do this. :^)
We're about to stop letting 0 NumericStyleValues pretend to be Lengths,
so this will break. As noted, the flex-basis property accepts
`<length>` not `<number>` so this is actually correct.
Only NumericStyleValue holds integers.
I'm not sure our current distinction between NumericStyleValue holding
an integer or non-integer is useful given it always returns a float.
:thonk:
In order to support intrinsic size keywords (such as fit-content), we
need to be able to calculate the intrinsic sizes of any element, not
just those that form their own formatting context.
When a non-FC-root element is passed to calculate_some_intrinsic_size(),
we now create a synthetic BFC to handle sizing of them.
...and keep a forwarding header around in VP9, so we don't have to
update all references to the class there.
In time, we probably want to merge LibGfx/ImageDecoders and LibVideo
into LibMedia, but for now I need just this class for the lossy
webp decoder. So move just it over.
No behvior change.
Introduces incomplete parsing of grid shorthand property. Only
<grid-template> part of syntax is supported for now but it is enough
to significantly improve rendering of websites that use this shorthand
to define grid :)
The path for floating, replaced elements must not fall through to the
path taken for floating, non-replaced elements. The former works like
inline replaced elements, while the latter uses a completely different
algorithm which doesn't account for intrinsic ratio. Falling through
overrides the correct value computed by the former.
Fixes#19061.
This fixes the issue when margin collapsing state was always reset if
a box has clear property not equal to none even if it does not actually
introduce clearance.
This was crashing on google.com with the linux chrome user agent,
interestingly it seems like this behavior may have been accidental as
only two of the three `parse_number()` were changed in f7dbcb6
Ignore anonymous block boxes when resolving percentage weights that
would refer to them, per the CSS 2 visual formatting model
specification. This fixes the case when we create an anonymous block
between an image which uses a percentage height relative to a parent
which specifies a definite height.
Fixes#19052.
