Code

function media_preprocess_media_reference_help(&$variables) {

  // Most of these attribute checks are copied from
  // template_preprocess_fieldset(). Our template extends
  // field-multiple-value-form.html.twig to provide our help text, but also
  // groups the information within a semantic fieldset with a legend. So, we
  // incorporate parity for both.
