Reviewed by Antti Koivisto.
We used to identify a null renderer in computedTransform() as a signal that the
"computed" value
for "transform" was requested rather than the "resolved" value. The difference
is significant
because a the "resolved" value for "transform" for an element that has
"display: none", and thus
no renderer is "none". However, we failed to identify this case and would
return the <transform-list>
type.
The same way that ComputedStyleExtractor::propertyValue() takes in an argument
to specify the value
type requested, we add a new argument to
ComputedStyleExtractor::valueForPropertyInStyle() which we
pass to computedTransform() to distinguish between the "display: none" case and
the "computed" value
case.
We also ask for the "computed" value from WebAnimation::commitStyles() and when
parsing keyframe styles
in the Web Animations API. We were already requesting such style through
ComputedStyleExtractor::propertyValue()
in the CSS Typed OM computedStyleMap() function.
Since this case was not tested before, we add some new assertions in an
existing WPT test to check that
setting "display: none" on an element with a "transform" set does indeed return
"none".
Incidentally, this brought a couple of new WPT PASS results for ::first-letter
and ::first-line.
