To get around the fact that we may have a owner_events = FALSE grab in

        * gtk/gtkmenu.c (gtk_menu_popup): To get around the fact
        that we may have a owner_events = FALSE grab in effect
        when we pop up a window, make a temporary grab on a
        different window, then grab on the real window. Fixes
        a problem where if a context menu popped up under the
        cursor, the first item would be stuck unselected.
