Fix JS state condition selectors to account for title replacement fields have different form names

Here's some code I put into test in title.module. I'm not sure it would be acceptable. And it only works for conditions that use the 'name' selector search.

/**
 * Fix any state conditions to use the new title field's name.
 */
function _title_field_process_states(&$form, $legacy_field_name, $replacement_field_name, $langcode) {
  foreach (element_children($form) as $key) {
    if (!empty($form[$key]['#states'])) {
      foreach ($form[$key]['#states'] as $state => &$conditions) {
        foreach ($conditions as $selector => $condition) {
          if (is_string($selector) && strpos($selector, '[name="' . $legacy_field_name . '"]')) {
            $replacement_field_actual_name = "{$legacy_field_name}[{$langcode}][0][value]";
            $new_selector = str_replace('[name="' . $legacy_field_name . '"]', '[name="' . $replacement_field_actual_name . '"]', $selector);
            $conditions[$new_selector] = $condition;
            unset($conditions[$selector]);
          }
        }
      }
    }

    // Recurse into nested form fields.
    _title_field_process_states($form[$key], $legacy_field_name, $replacement_field_name, $langcode);
  }
}
