Re: [mediacapture-screen-share] Let pages opt-in to capture. (#155)

> what about user state leaked in other ways, such as form controls or `:visited`? What's the story for that?

The plan is to rely on permission prompting and privacy indicators, and a list of other items [here](https://docs.google.com/presentation/d/1CeNeno5XuDhm1mpnVyE9eT14YKZgZUtgQsJfC8uqEpA/edit?ts=5fc7fcd2#slide=id.gaef31c926d_1_111)  — Any kind of sanitizing risks creating an ad-blocker blocker mode.

There's some pushback on the visibility requirement, since there are use cases of capturing e.g. a Google slides presentation in another open tab, without leaving the Google Meet tab, and basically remote-control the presentation with "next page", "previous page" commands out of band from there.

Both Chrome and Firefox (behind a pref) support capture of tabs that are in the background today FWIW.
