In order to deliver displayDidRefresh for WorkerThread requestAnimationFrame, we want a version of displayDidRefresh/DisplayRefreshMonitor that allows notifications without blocking on the main thread. We also likely want to match whatever framerate/throttling the underlying WebCore::Page is using, so that we slow down when hidden etc.
DisplayRefreshMonitor is heavily hardcoded towards using the main thread, so I think the easiest thing to do is add an API to EventDispatcher which handles this.
