Why is there no alt attribute associated with the poster attribute on a video element (or, what's the accessible name calculation on a video element

Hello,

I was wondering if there was ever any solution to the question asked here -
https://github.com/w3c/html/issues/1431 (Why is there no alt attribute
associated with the poster attribute on a video element (or, what's the
accessible name calculation on a video element)?


Thanks,
