Bean title does not display in Panels when bean loaded via EntityReference

I'm not sure this should be in the module, but here's the code I used to do it:

/**
 * Implements template_preprocess_panels_pane().
 *
 * Fix the pane title for beans loaded via entityreference fields.
 */
function mymodule_preprocess_panels_pane(&$variables) {
  $pane = $variables['pane'];

  // Only work with entityreference field panes.
  if ($pane->type == 'entity_field' && $variables['content']['#field_type'] == 'entityreference') {
    // Look for a bean object.
    foreach ($variables['content'] as $outer_key => $element) {
      if (is_numeric($outer_key) && array_key_exists('bean', $element)) {
        foreach ($element['bean'] as $key_inner => $bean_array) {
          $bean = $bean_array['#entity'];

          // Fix the title.
          $variables['content']['#title'] = $bean->title;
          $variables['title'] = $bean->title;

          // This will only work with one element in the array.
          break 2;
        }
      }
    }
  }
}

I think this is by design. Maybe something like this might be worth adding to a HowTo part of the documentation?
