The test `compositing/backing/backing-store-attachment-animating-outside-viewport.html` fails with "Threaded Time-based Animations" enabled. It works fine if the `setTimeout(…, 0)` call is replaced by a call to `requestAnimationFrame()` but I'm not sure whether it's appropriate to make that change.
