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).
