Re: [whatwg/fullscreen] Allow `requestFullscreen` after page reloaded (same session, if it had `document.fullscreenElement` in the previous document) (Issue #262)

michaelwasserman left a comment (whatwg/fullscreen#262)

Chromium shipped [Automatic Fullscreen Content Setting](https://chromestatus.com/feature/6218822004768768) for isolated context web apps (and enterprise policy).

There's also the [Capability Delegation](https://wicg.github.io/capability-delegation/spec.html#monkey-patch-to-fullscreen) of fullscreen, but there's no obvious way to transmit this across reload/nav.

There are tough usable security issues with drive-by sites entering fullscreen without a user activation; perhaps the same is still true of non-isolated context installed web apps.
