Interpolation can leave `padding-*` values as negative - this should be
handled by interpolation clamping it to the allowed range of values
but we don't yet do that. As a stop gap we can clamp this before setting
it in ComputedValues.
This fixes 3 crashes and gains us 11 passes in the imported WPT tests
An SVGLength can be read-only, e.g. all animVal values cannot be
modified. Implement this for all instantiations of SVGLength.
While we're here, add `fake_animated_length_fixme()` so we can easily
find all sites where we need to improve our animated length game.
We were failing to discriminate between DOM removals happening to SVG
elements cloned as part of an SVG use element instantiation.
When a "use source" element is removed, all clones of that source must
be updated to reflect the change. But when a "use clone" element is
removed, that's fine.
This was causing the surprising disappearance of use element subtrees,
seen for example on https://cal.com/
Some SVG presentation attributes are only supported on certain
elements. We now support these special cases for attributes and
elements that we currently have implemented.
Before this change, we were going through the chain of base classes for
each IDL interface object and having them set the prototype to their
prototype.
Instead of doing that, reorder things so that we set the right prototype
immediately in Foo::initialize(), and then don't bother in all the base
class overrides.
This knocks off a ~1% profile item on Speedometer 3.
Currently, this metadata is only provided on the insertion steps,
though I believe it would be useful to extend to the other cases
as well. This metadata can aid in making optimizations for these
steps by providing extra context into the type of change which
was made on the child.
This change adds computation of ARIA roles for a number of SVG elements
for which, if the element meets the SVG spec criteria for inclusion in
the accessibility tree, the computed ARIA role should be
“graphics-symbol”, and should otherwise be “generic”.
This change also adds similar role computation for the SVG foreignObject
element (the role for which, if the element meets the SVG spec criteria
for inclusion in the accessibility tree, should be “group”, and should
otherwise be “generic”).
Resulting in a massive rename across almost everywhere! Alongside the
namespace change, we now have the following names:
* JS::NonnullGCPtr -> GC::Ref
* JS::GCPtr -> GC::Ptr
* JS::HeapFunction -> GC::Function
* JS::CellImpl -> GC::Cell
* JS::Handle -> GC::Root
We currently have 2 virtual methods to inform DOM::Element subclasses
when an attribute has changed, one of which is spec-compliant. This
patch removes the non-compliant variant.
LibWeb keeps growing and the Web namespace is filling up fast.
Let's put DOM stuff into Web::DOM, just like we already started doing
with SVG stuff in Web::SVG.
