    mime-widget-text: The "draw" signal has gone away
    
    We would like to create cite-bars at "draw" time, but that signal has
    been removed. Connecting to "realize" or "map" seems to be too early in
    the process, as the cite-bars are not drawn. Using an idle handler gets
    them shown, so we'll use that fix. There may be a slight delay between
    the message being rendered and the cite-bars being added to it, but for
    now it seems to be a necessary price to pay.
