I’m not sure what context you were using it in? It still works for non-HTML content types, can be used for mjpeg video streams, etc but you shouldn’t be able to use it to replace the previously rendered HTML contents of a frame.
Hmm I don't remember if we did dom manipulation in there. It was definitely used for video streaming though. There's a good chance we only used it for mjpeg and canvas shenanigans.
