commit a91d15b4b983aef7c63eace0db0868aa890927b3

    Improve performance generating status bar in web apps
    
    * Defer to the default script's presentObject() because we've already
      done all the work to ensure we have the right contents.
    * Don't bother checking for and possibly generating ancestors; we should
      just be presenting the status bar.
