CachePluginBase::postRender docblock not using @code for code example

API page: https://api.drupal.org/api/drupal/core%21modules%21views%21src%21Plugin%...

   * Example usage. If it is known that the view is a node view and that the
   * primary field will be a nid, you can do something like this:
   *
   * <!--post-FIELD-NID-->
   *
   * And then in the post render, create an array with the text that should
   * go there:
   *
   * strtr($output, array('<!--post-FIELD-1-->', 'output for FIELD of nid 1');
   *
   * All of the cached result data will be available in $view->result, as well,
   * so all ids used in the query should be discoverable.

Code example in this docblock should be enclosed with @code-@endcode.
