Computed Style().transform/opacity should return style values updated by Time Stamp::Now() instead of the most recent refresh time on busy frame .
This bug is related to bug 1167519. getComputedStyle() flushes styles but it's against the most recent refresh time. If getComputedStyle() is called for styles on the compositor animations in a busy frame, we will get a different value from what we are seeing the animation on the compositor. From CSS transition spec: > Therefore if a script queries the computed style of a property as it is transitioning, > it will see an intermediate value that represents the current animated value of the property Attaching file is a modification of attachment 8610350 [details] in bug 1167519. On Chrome getComputedStyle().transform in the file returns a value close to 230, but we don't.
I'm not quite sure I understand what this bug covers that bug 1167519 does not -- perhaps it is about the time in between triggering the new transition and when we update the 'from' keyframe?
