Details

In Bug 1741255, we'd like to use TriggerNow() for scroll-animations in PlayNoUpdate() and PauseNoUpdate(). However, it's possible that GetCurrentTimeAsDuration() returns nullptr, and so we don't trigger it in this case (i.e. this animation may be always pending). We have to address this issue in this bug.

Besides, we should check Chrome's behavior, when animation-start event gets fired if the animation is linked to an element that was initially in display:none subtree but gets visible later.
