I'll rephrase to try to better describe what I had observed. - Pivot app in OS window 'A' has a focused TextInput. - OS window 'A' is decorated as active by the OS - The same Pivot app has a 2nd Display in OS window 'B' - User clicks on the chrome of OS window 'B' to activate window 'B' - The TextInput retains focus, meaning it will receive key stroke events, even though it is not a descendant of OS window 'B'.
