Could <Teleport> leverage the new moveBefore() API to preserve state?

[Youhan]

Hi team,

I recently came across the new moveBefore() API, which allows moving DOM nodes without resetting their internal state (e.g., videos keep playing, iframes don't reload).

Reference: https://developer.chrome.com/blog/movebefore-api

Currently, <Teleport> seems to rely on remove/insert, which causes media to reset when the target changes.

I was wondering if it might be feasible for Vue to progressively enhance runtime-dom to use moveBefore when available? This would make features like "Picture-in-Picture" (moving a video player to a different container) seamless without needing manual DOM manipulation.

Is this something that would fit into the current renderer architecture?

Thanks!
