At least in WebKit browsers, when the resolution of a video stream changes, the corresponding video element triggers a resize event. Is there any documentation available on this? Or any references or discussions? I haven't been able to find anything.

Whenever the natural width or natural height of the video changes [...]
fire an event named resize at the media element.
