[csswg-drafts] [web-animations-1] Playing an animation does not account for an inactive timeline (#4379)

JTensai has just created a new issue for https://github.com/w3c/csswg-drafts:

== [web-animations-1] Playing an animation does not account for an inactive timeline ==
https://drafts.csswg.org/web-animations/#playing-an-animation-section

If an animation is supplied an inactive timeline (e.g. a ScrollTimeline using a scroller with style="display:none") it will fail.

Before setting `hold_time` in `play()` we need to first check that there is an active timeline. If not, we should not start the animation until the timeline has become active.
