In Windows 10, holding down alt and then pressing tab brings up the new Task Switch Window. Focus correctly goes to the newly selected app in the contained grid. However, then a new focus event is fired on the task swiching window itself. Therefore when pressing tab a second time, the focus ancestory of the newly selected item in the grid is announced again. We should suppress focus events on this task switch window itself as focus is always within it, not on it.
