Re: [csswg-drafts] [web-animations-1] Play state of an animation with an unresolved timeline (#5400)

Firefox is passing due to not having the test for startTime being unresolved in the idle check. 
https://searchfox.org/mozilla-central/source/dom/animation/Animation.cpp#480

The following test was updated with the algorithm change and currently fails on Firefox and Safari:
wpt/web-animations/timing-model/animations/setting-the-timeline-of-an-animation.html

Once setTimeline is supported in Blink the following tests will have new failure reasons based on the plate state:
wpt/css/css-animations/event-dispatch.tentative.html
wpt/css/css-transitions/event-dispatch.tentative.html

See the tests titled "Active -> Idle, setting Animation.timeline = null"

Gladly make the PR
