Look closely at the Firefox permission dialog here, and you'll see it

Interesting--is that "exact" constraint documented somewhere?
See [1] and [2].
Does Chrome support it as well?
Only if you use adapter.js, the official WebRTC polyfill. [3]
That's because Chrome still uses an older `mandatory`/`optional`
constraints syntax, which can express the same thing (`exact` has the
same effect as `mandatory`).
