     * OpenDialogCommand in that a modal prevents other interactions on the page
     * until the modal has been completed. Drupal provides a built-in modal for
     * this purpose, so no selector needs to be provided.
     *
     * @param string|\Stringable|null $title
     *   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.
