Max length does not appear on media library upload form

Problem/Motivation

I have created custom field in media where user can add up to 250 character and made use of maxLength. When I go to /media/add/image, it all looks good. I can see the character limit text, however when I add image using wysiwyg ckeditor field and I do not see that.

I tried adding form element values/attributes as well using MODULE_NAME_field_widget_form_alter described in this documentation ( https://www.drupal.org/docs/contributed-modules/maxlength/code-usage → ) and I still so no change. 

/**
 * Implements hook_field_widget_form_alter().
 */
function MY_MODULE_field_widget_form_alter(&$element, Drupal\Core\Form\FormStateInterface $form_state, $context) {
  $items = $context['items'];
  $field = $items->getName();

  if ($field == "field_media_caption") {
    if (key_exists('form_id', $form_state->getBuildInfo())) {
      $build_info = $form_state->getBuildInfo();
      if ($build_info['form_id'] == 'media_library_add_form_upload') {
        $element['#maxlength_js'] = TRUE;
        $element['value']['#maxlength_js'] = TRUE;

        $maxlength_js = 500;
        $element['value']['#attributes']['maxlength'] = $maxlength_js;
        $element['#attributes']['maxlength'] = $maxlength_js;

        $maxlength_js_label = 'Contenido limitado a @limit caracteres, quedan: <strong>@remaining</strong>';
        $element['#attributes']['maxlength_js_label'][] = $maxlength_js_label;
        $element['value']['#attributes']['maxlength_js_label'][] = $maxlength_js_label;
      }
    }
  }
}

Surely, I'm not the first one to experience this. Can someone guide me if there is anything that I have missed?

    Got it working for a menu link field that way.

          $form['title']['widget'][0]['value']['#maxlength'] = 25;
      $form['title']['widget'][0]['value']['#attributes']['data-maxlength'] = 25;
      $form['title']['widget'][0]['value']['#maxlength_js'] = TRUE;

    Guess you just need to add that 'data-maxlength' to your example above.
    For my case it needed to be inside of $element['widget'][0]['value'] to get it working.
    The documentation says it different.
