Cancel the `requestAnimationFrame` in the API when cancelling rendering

[Snuffleupagus]

Errors related to this requestAnimationFrame show up intermittently when running the integration-tests on the bots, however I've been unable to reproduce it locally. Hence I cannot guarantee that it's enough to fix the timing issues, however this should be generally safe since the requestAnimationFrame invokes the _next-method and the first thing that one does is check that rendering hasn't been cancelled.
