Allow screens to stay in their parent even when all corners are outside parent - if there is some overlap

[TodePond]

eg: When you rotate a screen, it often pops out of its parent even though you would expect it to stay in the parent

[100xCode]

wouldn't that be confusing?
It would be difficult to know if a screen is just in front of another screen, or if it's in front of + inside of another screen.
