CONSOLE WARNING: Listener added for a 'DOMSubtreeModified' mutation event. This event type is deprecated, and will be removed from this browser VERY soon. Usage of this event listener will cause performance issues today, and represents a large risk of imminent site breakage. Consider using MutationObserver instead. See https://chromestatus.com/feature/5083947249172480 for more information.
This tests that we don't crash while creating a video element while a DOMSubtreeModified even handler is registered.

If you can see the movie below, the test passed.

SUCCESS: The test ran without crashing
