    modalDialog: Request HEIGHT_FOR_WIDTH
    
    All our modal dialogs are given a fixed width and grow vertically
    as necessary. Set the request mode accordingly, so that wrapped
    labels are considered correctly during size request, and not only
    at allocation time (where they'll either take away from the padding
    or even cause the dialog to overflow).
