  // than json rendered even when the display was set to export csv or xml.

  // We intentionally implement this different from the parent method because
  // $this->displayHandler->getContentType() will always return json due to
  // the request's header (i.e. "accept:application/json") and
  // we want to be able to render csv or xml data as well in accordance with
  // the data export format configured in the display.

  // This option can be configured in the CSV Settings section of the data
  // export.
