PIP: Only hide when both the window and the PIP view are in the same monitor

### Expected Behavior
PIP should only hide if the window is also on the same monitor as the PIP view. We're hiding the view to avoid covering the same window anyways, and if it's on a separate display then we shouldn't have to worry about covering the window

### Story Time!
I had a presentation in class and wanted to use PIP to show parts of different windows on the projector while i was controlling them on my main screen. Problem is that when you focus into the window the PIP view disappears even if it's on the same monitor.
