  // When dealing with saving menu items, the order in which these items are
  // saved is critical. If a changed child item is saved before its parent,
  // the child item could be saved with an invalid path past its immediate
  // parent. To prevent this, save items in the form in the same order they
  // are sent by $_POST, ensuring parents are saved first, then their children.
