      6 // presented to create or edit a bookmark.  There can only ever be a single
      7 // bubble open, so the class presents only static methods, and handles the
      8 // singleton behavior for you.  It also handles the object and widget
      9 // lifetimes, destroying everything and possibly committing any changes when
     10 // the bubble is closed.
