This is the expected behavior per the HTML spec. Fixes an issue where
styling these elements wouldn't have the expected effect unless you also
set the display property.
Instead of allowing arbitrarily large values (which could eventually
overflow an i32), let's just cap them at the same limit as Firefox does.

This change will make it easier to disable screenshot comparison tests
on a specific platform or have per-platform expectations.
Additionally, it's nice to be able to tell if a ref-test uses a
screenshot as an expectation by looking at the test path.
Utf16View currently assumes host endianness. Add support for specifying
either big or little endianness (which we mostly just pipe through to
simdutf). This will allow using simdutf facilities with LibTextCodec.
The one behavior difference is that we will now actually fail on invalid
code units with Utf16View::to_utf8(AllowInvalidCodeUnits::No). It was
arguably a bug that this wasn't already the case.
Areas are disassembled into boundary lines on `build_grid_areas()` step,
so we can always use them to find grid item's position during placement.
This way we support both ways to define area: `grid-template-areas` and
implicitly using `-start` and `-end` boundary line names.
If no header includes the prototype of a function, then it cannot be
used from outside the translation unit it was defined in. In that case,
it should be marked as `static`, in order to avoid possible ODR
problems, unnecessary exported symbols, and allow the compiler to better
optimize those.
If this warning triggers in a function defined in a header, `inline`
needs to be added, otherwise if the header is included in more than one
TU, it will fail to link with a duplicate definition error.
The reason this diff got so big is that Lagom-only code wasn't built
with this flag even in Serenity times.
This matches libwebp (see ZeroFillCanvas() call in
libwebp/src/demux/anim_decode.c:355 and ZeroFillFrameRect() call
in line 435, but in WebPAnimDecoderGetNext()) and makes files
written e.g. by asesprite look correct -- even though the old
behavior is also spec-compliant and arguably makes more sense.
Now nothing looks at the background color stored in the file.
See PR for an example image where it makes a visible difference.

- Change min track sizing function to be "auto" when flex size is
specified.
- Never check if min track sizing funciton is flexible, because only
max is allowed to be flexible.
- Address FIXME in automatic_minimum_size to avoid regressions after
making two fixes mentioned above.
The change causes Tests/LibWeb/WPT/run.sh to run an arbitrary subset of
tests you give it as arguments. If you don’t specify any arguments, it
has the same behavior as it does without this patch: It just runs an
explicit subset of test names hardcoded into the script.
Otherwise without this change, Tests/LibWeb/WPT/run.sh doesn’t have the
ability to run any tests other than the explicit subset of test names
hardcoded into the script
We currently have 2 base64 coders: one in AK, another in LibWeb for a
"forgiving" implementation. ECMA-262 has an upcoming proposal which will
require a third implementation.
Instead, let's use the base64 implementation that is used by Node.js and
recommended by the upcoming proposal. It handles forgiving decoding as
well.
Our users of AK's implementation should be fine with the forgiving
implementation. The AK impl originally had naive forgiving behavior, but
that was removed solely for performance reasons.
Using http://mattmahoney.net/dc/enwik8.zip (100MB unzipped) as a test,
performance of our old home-grown implementations vs. the simdutf
implementation (on Linux x64):
Encode Decode
AK base64 0.226s 0.169s
LibWeb base64 N/A 1.244s
simdutf 0.161s 0.047s
When traversing the layout tree to find an appropriate box child to
derive the baseline from. Only the child's margin and offset was being
applied. Now we sum each offset on the recursive call.
The spec says to just call the XML serialization algorithm, but it
returns the "outer serialization", and we need the "inner" one. Let's
just concatenate serializations of children; then the result produced is
similar to one from Blink or Gecko.
This method puts the given node and all of its sub-tree into a
normalized form. A normalized sub-tree has no empty text nodes and no
adjacent text nodes.
Because `nan:arithmetic` and `nan:canonical` aren't bound to a single
bit pattern, we cannot check against a float-containing SIMD vector
against a single value in the tests. Now, we represent `v128`s as
`TypedArray`s in `testjs` (as opposed to using `BigInt`s), allowing us
to properly check `NaN` bit patterns.
Some spec-tests check the bit pattern of a returned `NaN` (i.e.
`nan:canonical`, `nan:arithmetic`, or something like `nan:0x200000`).
Previously, we just accepted any `NaN`.
Previously the input element was displayed with value 0, when no value
was set in the HTML. Now it uses `value_sanitization_algorithm()`, which
will calculate the default value.
In `value_sanitization_algorithm()` there was a logical mistake/typo.
The comment from the spec says "unless the maximum is less than the
minimum".
The added layout test would fail without the code changes.
Fixes#520
When the min option is given the read will only be fulfilled when there
are min or more elements available in the readable byte stream.
When the min option is not given the default value for min is 1.
