const [REQUEST, EXIT, ELEMENT,, EVENT] = map doesn't match the [New WebKit] if

 [
    'webkitRequestFullscreen',
    'webkitEnterFullScreen',
    'webkitExitFullscreen',
    'webkitFullscreenElement',
    'webkitFullscreenEnabled',
    'webkitfullscreenchange',
    'webkitfullscreenerror',
  ]

@TianbinTobin You're right - That's what happens when you open PRs late at night 😅.
Just ammended my commit!

Hi there! Thanks for the work on this!

Unfortunately, this doesn't completely fix it. If target changes (i.e. null -> <video>), the map isn't updated, leading to REQUEST, EXIT, ELEMENT,, EVENT being invalid for the specific target.

@N3mezis Im aware of this. Initial work for properly handle it in this PR: #2904

My plan is to completely refactor this function afterwards. It didn't fully fix Safari iOS either, since some devices still rely on the deprecated (according to Apple docs) webkitEnterFullScreen (notice the case of S)

@N3mezis Check #2915
