Review comment:
Running this only within `if (!!requestFullscreen && !!exitFullscreen) { ...
}` will result in the fullscreen option being available only if there is a
vendor-prefixed version of those functions available. If a browser implements
the standard but no vendor-prefixed version, the option will not be present.
