 /**
  * Wrapper for handling AJAX forms.
  *
  * Wrapper around \Drupal\Core\Form\FormBuilderInterface::buildForm() to
  * handle some AJAX stuff automatically.
  * This makes some assumptions about the client.
  *
  * @param \Drupal\Core\Form\FormInterface|string $form_class
  *   The value must be one of the following:
  *   - The name of a class that implements \Drupal\Core\Form\FormInterface.
  *   - An instance of a class that implements \Drupal\Core\Form\FormInterface.
  * @param \Drupal\Core\Form\FormStateInterface $form_state
  *   The current state of the form.
  *
  * @return \Drupal\Core\Ajax\AjaxResponse|string|array
  *   Returns one of three possible values:
  *   - A \Drupal\Core\Ajax\AjaxResponse object.
  *   - The rendered form, as a string.
  *   - A render array with the title in #title and the rendered form in the
  *   #markup array.
