The HTMLMediaElement will need to stop fetching processes when its load algorithm is invoked while a fetch is ongoing. We don't have a way to really stop the process, due to the way it runs on nested deferred task invocations. So for now, this swaps the fetch callbacks (e.g. to process a fetch response) with empty callbacks.
