Implement full screen media like Safari on macOS

[buggydonkey]

Hello,

Currently on websites such as Netflix, full screening videos brings up a layer that sits atop everything in the current Desktop, even notifications. This is somewhat sub-optimal in comparison to the standard macOS implementation (as in iOS) as it hides notifications, it prevents desktop switching with gestures, and generally is not in line with the standard macOS experience.
