If two popup windows are displayed with the coherence feature enabled on both, then
the popup window that is displayed first will be the dominant window.
Coherence is most often used on popup windows that take a large area of the OIT display. When they are displayed,
they often completely cover smaller popup windows that are already on display, making it difficult to access the
covered popup windows.
