Wrap tag classes are not being inserted

The (Wrap tag class) is not being inserted into the HTML.
The line 117 of title.field.inc needs to change from:

if (!empty($settings['title_class'])) {
      $element['#attributes'] = array('class' => $settings['title_class']);
    }

Changed to:

    if (!empty($settings['title_class'])) {
      $element['element']['#attributes'] = array('class' => $settings['title_class']);
    }
