It would be better to break “window on top” property of a window when modal dialog is created.

When we have a top level window with property "Qt::WindowStaysOnTopHint" and a small modal dialog is crated if that goes behind this "window on top" it is not possible at all to interact with the application and eventually needs to be killed.

It would be nice if window with flag Qt::WindowStaysOnTopHint should loose its this property so that interaction with the application could still be possible.
