Fix calls to element.animate() with positive delays not being composited
We were only snapshotting compositor keyframes when there was an animation
update.
In the case of element.animate() with a positive delay there's
no CSS animation change to the animation engine nor are there any effects
to be applied. Previously we would early out in this situation, this
change ensures we still look for KeyframeEffects that require
compositor snapshotting.
