Code

  // backup of the original fields.

  // We can not just return a render array with a clone of a filtered view
  // because views assigns the view object just before rendering, which
  // results in all fields being rendered in each region.
  // We therefore have to force rendering outside of the render context of
  // this request.

    // the renderer. These two methods are however defined and tested by core.
    // There is no need for them to be tested by our unit tests.
