Done. Changed not to show the menu if there is no custom action.

+    customActionsMenu.addMenuItem(Msgs.getMsg('panel_menu_item_none'),
+        '' /* menuItemShortcut */, '' /* menuItemBraille */,
+        null /* callback */);
+  }

   // Activate either the specified menu or the first menu.
   var selectedMenu = Panel.menus_[0];
   for (var i = 0; i < Panel.menus_.length; i++) {
