Emilio Cobos Álvarez 2a5ee3bf93 servo: Merge #19016 - style: Fix detection of animations to avoid style flushing in getComputedStyle (from emilio:animation-avoid-flush-not-quite); r=hiro
This fixes multiple things:

 * EffectCompositor was using the light tree instead of the flat tree.

 * When we insert an element inside the document, we may not style it right away
   (we mark it for lazy frame construction with the NODE_NEEDS_FRAME). Since we
   trigger animations and transitions from the traversal, we can't skip flushing
   if we call getComputedStyle on any of those.
