The Video element allows pasting a YouTube URL or a YouTube ID.
For YouTube Shorts, the URL is something like https://youtube.com/shorts/kh1SmhRr1Hc
This will result in an invalid iframe src and wont work: src="https://www.youtube.com/embed/https://youtube.com/shorts/kh1SmhRr1Hc?wmode=opaque&rel=0&enablejsapi=1"
thank you for bug report. That’s true, YouTube shorts (and live links) are not supported for Video element.
I did create a task internally to support it.
