PopupMenu2 doesn't collapse when mouse click outside menu.

This is probably the same issue as with #2291. The problem is with dojo.widget.PopupManager?.registerWin()

  this.registerWin = function(/*Window*/win){
// summary: register a window so that when clicks/scroll in it, the popup can be     closed automatically
    
if(!win.__PopupManagerRegistered)
    {
      dojo.event.connect(win.document, 'onmousedown', this, 'onClick');
      dojo.event.connect(win, "onscroll", this, "onClick");
      dojo.event.connect(win.document, "onkey", this, 'onKey');
      win.__PopupManagerRegistered = true;
      this.registeredWindows.push(win);
    }
  };

'this' referenced in each dojo.event.connect() refers to the function itself where as it should refer to dojo.widget.PopupManager?. Changing the function to the following works fine.

   this.registerWin = function(/*Window*/win){
     // summary: register a window so that when clicks/scroll in it, the popup can be closed automatically
     if(!win.__PopupManagerRegistered)
     {
       dojo.event.connect(win.document, 'onmousedown', dojo.widget.PopupManager, 'onClick');
       dojo.event.connect(win, "onscroll", dojo.widget.PopupManager, "onClick");
       dojo.event.connect(win.document, "onkey", dojo.widget.PopupManager, 'onKey');
       win.__PopupManagerRegistered = true;
       this.registeredWindows.push(win);
     }
  };
