   * this purpose, so no selector needs to be provided.
   *

   *   The title of the dialog.
   * @param string|array $content
   *   The content that will be placed in the dialog, either a render array
   *   or an HTML string.
   * @param array $dialog_options
   *   (optional) Settings to be passed to the dialog implementation. Any
   *   jQuery UI option can be used. See http://api.jqueryui.com/dialog.
   * @param array|null $settings
   *   (optional) Custom settings that will be passed to the Drupal behaviors
   *   on the content of the dialog. If left empty, the settings will be
   *   populated automatically from the current request.
