script: Avoid needless `ChangeRunningAnimationsState` messages during typical `requestAnimationFrame()` animations.
This skips useless message traffic when `requestAnimationFrame()` is
called during an animation frame callback. It reduces CPU usage of the
following snippet by 49%:
<script>
function foo() {
requestAnimationFrame(foo);
}
</script>
<button onclick="foo()">Start rAF</button>
Partially addresses #9844.
