I don't like leaving this trap. Reusing the compound-child mechanism
seems a little peculiar to me. Might it be best to simply add new

and implement a custom show_all for gtkmenushell to handle that?

(We could make that gtk_widget_set_no_show_all(), but then custom 
show_all implementations wouldn't get it right, so it wouldn't really
work universally.)
