    Fixed GtkFileChooserDefault to handle cases of being in an embedded dialog.
    
    This involves checking the toplevelness of new toplevels before connecting
    but not the *old* ones for disconnecting signals. Also take care of handling
    a row_reference that becomes invalid over the course of reparenting the
    filechooser into another parent.
