I don't understand that logic. There is no reason why a window should not be able to directly own a control that protrudes beyond its outermost border. At a bare minimum, the "child window" used to implement an element should directly be descended from the "parent window" of the application so that any attempt to capture an image of the parent window includes all child windows. This was clearly a limitation of the chosen implementation rather than an inherent limitation of all possible implementations.
