Cover Block: Add option to pause background videos

[hanneslsm]

What problem does this address?

With the cover block it's possible to add videos as a background.
I just came across https://openai.com/ website that also uses a video in the background, but additionally a "Pause Video" button on the right bottom corner.
I think this is a nice feature and it would make sense to add this to the cover block.
Also, I'd imagine this could enhance a11y, but some experts here can assess that better :)

What is your proposed solution?

• Either a "pause" block that can be used within the cover block
• or a toggle to show and hide play/pause controls - similar as we have now with the lightbox fullscreen icon already.

This is actually an accessibility requirement: https://www.w3.org/WAI/WCAG21/Understanding/pause-stop-hide.html

There's probably easier ways, but for anyone searching like I did, I made a makeshift solution to achieve an accessible block. Mind you - you have to add the script and html-button yourself:
