Functions to support theming in the Umami theme.

Code

function umami_form_alter(array &$form, FormStateInterface $form_state, $form_id) {
  $form_object = $form_state
    ->getFormObject();
  if ($form_object instanceof ViewsForm && strpos($form_object
    ->getBaseFormId(), 'views_form_media_library') === 0) {

    // The conditional below exists because the media-library-views-form class
    // is currently added by Classy, but Umami will eventually not use Classy as
    // a base theme.
    // @todo remove conditional, keep class addition in
    //   https://drupal.org/node/3110137
    // @see https://www.drupal.org/node/3109287
