Allow `screenfull.request` to timeout

[mxdvl]

When running Playwright tests, screenfull.request hangs indefinitely. I believe this may be because the iframe does not have allowfullscreen, but I believe that there should be a configurable timeout if the fullscreen request does not succeed after a while.

If someone else reacts with a 🚀 I’ll have a go at implementing this myself 😁
