Not user generated accessibility events can change the interrogation allowing window.
1. Events not generated by the user can change the interrogation allowing window
unpredicatably. For example when a ListView lays out its children it fires an
accessibility events and changes the currently active window while the user
interaction may be happening in another window say a dialog. Now the interrogation
allowing window is changed when a new window is shown or the user has touch
explored it.
