Re: [mediacapture-screen-share] Suggest User Agents treat a captured tab as visible (#307)

> @youennf did you check if the captured tab's visibility was tied to the capturing tab's visibility?

I didn't, given it can be sent to remote peers, my guess it that it does not depend on the capturing tab's visibility.
It would be nice to get input from Chrome's implementors.

This is JS observable via `document.visibilitystate` and its related change event.

If there is no guidance, I think it is worth adding a section describing the potential issues.
