Accessory windows are windows that, when activated, will activate their parent and bring all other accessory windows of that parent to the front of the window stack. Accessory windows can only be active input windows. The accessory window's parent is always the active window regardless of whether it is also the active input window. In order to route input correctly, input is now sent to the active input window, which can be any accessory window or their parent, or any regular window.
