Bug 1760216 [wpt PR 33207] - Call RestartAnimationOnCompositor() whether or not performing_reattach is true., a=testonly

Automatic update from web-platform-tests
Call RestartAnimationOnCompositor() whether or not performing_reattach is true.

Even when performing_reattach is false, it's important to call
RestartAnimationOnCompositor so that effect_changed will be true, so
that if we restart the animation, the compositor gets the new element
ID.

Without this change, and with https://crrev.com/c/3498292, the added
test fails when run in virtual/threaded/.
