Reproduced this black screen on M1 Mac as well.

Video seems to come in when the window loses and regains focus.

Template cloning also seems to also affect autoplay behavior of any video.

I noticed this since it breaks in JavaScript frameworks that rely on this method for cloning nodes to do their templating. Lit uses `document.importNode` which seems to be fine, a number of other frameworks use this method. I'm the maintainer of Solid(https://github.com/solidui/solid) one such framework affected by this.
