  // to generate menu tree parameters, and those take the active menu trail
  // into account. Therefore, we must vary the rendered menu by the active
  // trail of the rendered menu.
  // Additional cache contexts, e.g. those that determine link text or
  // accessibility of a menu, will be bubbled automatically.
