Code

public function alterConfigureForm(array &$form, FormStateInterface $form_state) {
  if ($this
    ->isAjax()) {

    // Allow the forms loaded into off-canvas to display status messages.
    if (!isset($form['status_messages'])) {
      $form['status_messages'] = [
        '#type' => 'status_messages',
      ];
    }

    // @todo static::ajaxSubmit() requires data-drupal-selector to be the same
    //   between the various Ajax requests. A bug in
    //   \Drupal\Core\Form\FormBuilder prevents that from happening unless
    //   $form['#id'] is also the same. Normally, #id is set to a unique HTML
    //   ID via Html::getUniqueId(), but here we bypass that in order to work
    //   around the data-drupal-selector bug. This is okay so long as we
    //   assume that this form only ever occurs once on a page. Remove this
    //   workaround in https://www.drupal.org/node/2897377.
    $form['#id'] = Html::getId($form_state
      ->getBuildInfo()['form_id']);
  }
