Bug 1550190 [wpt PR 16398] - [Animation Worklet] Playing a running animation should not crash, a=testonly

Automatic update from web-platform-tests
[Animation Worklet] Playing a running animation should not crash

Upon playing a worklet animation we attach the animation to the
worklet animation controller. Playing the running animation again leads
to duplicated attaching. Rather, the second animation.play() should be
a no-op.
