+ Add new WPT tests to check we correctly compute implicit keyframes when a 0% and/or 100% keyframe
+ is defined but only specifies a timing function. One test checks the output of getKeyframes() and
+ the other that we correctly account for the implicit vaues when computing styles.

+
+ REGRESSION (r287524): hihello.me does not show sliding sheet at the bottom of the page
+ https://bugs.webkit.org/show_bug.cgi?id=236838
+ rdar://88672183
+
+ Reviewed by Dean Jackson.
+
+ When we fixed bug 234799 we fixed the behavior of keyframe deduplication in
+ Style::Resolver::keyframeRulesForName(). While this was a good fix, code that
+ relied on the KeyframeList that would eventually be yielded from that function
+ did not quite correctly add implicit keyframes for the 0% and 100% case in some
+ relatively obscure situation.
+
+ The site hihello.me made this shortcoming apparent. This site has this odd keyframe rule:
+
+ from, 60%, 75%, 90%, to {
+ animation-timing-function: cubic-bezier(0.215, 0.61, 0.355, 1);
+ }
+
+ It appears the intention of the author with this rule is to replicate the timing function
+ on multiple keyframes. However, this does not work. This timing function will not be used
+ for *anything* since if a rule is specified without an animation-timing-function value it
+ will use the value set on the element, not one on a different keyframe.
+
+ This also means that while there are explicit 0% and 100% keyframes, they are not adequate
+ to then compute implicit properties since the timing function wouldn't match the default
+ timing function (unless the element that those keyframes are applied to would happen to
+ specify that exact same timing function).
+
+ To correctly handle this, we need to do several things.
+
+ First of all, we remove the implicit keyframe code found in KeyframeEffect::getKeyframes()
+ and let KeyframeList::fillImplicitKeyframes() do all the work to correctly fill-in values
+ for properties not eplicitly specified on a 0% or 100% keyframe.
+
+ This means we need to improve that function to correctly do the task that it's supposed to
+ do. Now provided with a KeyframeEffect and an underlying style as parameters, for 0% and
+ 100% it correctly:
+
+ 1. compiles a list of implicit properties for the given keyframe
+ 2. find a compatible keyframe for the implicit properties or create one
+ 3. set the implicit properties on that compatible keyframe to match the values found
+ in the underlying style
+
+ This correctly takes cares of calls to getKeyframes() as well as the generation of keyframes
+ passed down to RenderLayerBacking when starting an accelerated animation.
+
+ But RenderLayerBacking also had some outdated assumptions on the KeyframeList it receives.
+ Indeed, it would always assume that a 0% or 100% keyframe would *always* specify properties
+ for the animated property. That was incorrect since we correctly deduplicate keyframes and
+ having several 0% or 100% keyframes is perfectly valid. Now we don't give special treatment
+ to 0% or 100% keyframes in RenderLayerBacking::startAnimation() and always check that a keyframe
+ features values for the animated property before creating an animation value to send down
+ to GraphicsLayer.
+
+ Finally, another place we make assumptions on implicit keyframes was when resolving styles
+ as effects are applied in KeyframeEffect::setAnimatedPropertiesInStyle(). There we assumed
+ that a 0% or 100% keyframe would always qualify as a keyframe containing the animated property,
+ whereas the steps for resolving styles as specified by the Web Animations specification has
+ logic to deal with the case where we don't find a 0% or 100% keyframe with an explicit value
+ for the animated property. So we simplified the checks there to only ever check for an
+ explicit value.
+
+ This rather obscure way to specify keyframes was not previously tested by WPT, so this patch
+ improves the testing coverage in a way that would have caught this regression in the first place.
