    filechoosernativeportal: stuff the current filter into options
    
    We need to tell the portal what filter is supposed to be selected by
    default, or it will just pick the first one, which could be wrong and
    annoying.
    
    This will require updated xdg-desktop-portal and xdg-desktop-portal-gtk
    to work properly.
