/**
 * PopupButtonWidgets toggle the visibility of a contained {@link OO.ui.PopupWidget PopupWidget},
 * which is used to display additional information or options.
 *
 *     @example
 *     // A PopupButtonWidget.
 *     const popupButton = new OO.ui.PopupButtonWidget( {
 *         label: 'Popup button with options',
 *         icon: 'menu',
 *         popup: {
 *             $content: $( '<p>Additional options here.</p>' ),
 *             padded: true,
 *             align: 'force-left'
 *         }
 *     } );
 *     // Append the button to the DOM.
 *     $( document.body ).append( popupButton.$element );
 *
 * @class
 * @extends OO.ui.ButtonWidget
 * @mixes OO.ui.mixin.PopupElement
 *
 * @constructor
 * @param {Object} [config] Configuration options
 * @param {jQuery} [config.$overlay] Render the popup into a separate layer. This configuration is useful
 *  in cases where the expanded popup is larger than its containing `<div>`. The specified overlay
 *  layer is usually on top of the containing `<div>` and has a larger area. By default, the popup
 *  uses relative positioning.
 *  See <https://www.mediawiki.org/wiki/OOUI/Concepts#Overlays>.
