Prior to this commit it was possible to get the menu bar deactivated by moving the mouse to an adjacent menu item and then back again. If the movement was quick enough the corresponding PopupMenu would be dismissed and created again before the dismissal's async command handler would run. The command handler would see that the dismissed menu's index and the currently activated index are equal and deactivate the menu bar.
