Make always-on-top windows persist across workspaces

For Picture-in-Picture, we use an always-on-top window to keep the video player on top of other applications.

For users that use workspaces on macOS, this is only a half-measure, since it's easy to lose the player window between workspaces. Ideally, the player window should persist between workspaces.

Chromium is able to do this with their non-native player window, so we can likely leverage the same technique.

I just rechecked in latest Dev Edition. The way picture-in-picture is implemented is of no use to a mac user if he is using apps in fullscreen mode and across multiple workspaces.
Picture-in-picture should behave like Helium does. For reference see

Besides that... Great Feature!
