JQMIGRATE: jQuery.fn.click() event shorthand is deprecated

[dotherightthing]

$expandButton.click(function (event) {
      var triggered = !event.originalEvent; // prevent the click bubbling up to the viewer, creating an infinite loop

      event.stopPropagation();
      var $currentGallery = $(event.target).parents('.wpdtrt-gallery').eq(0);
      wpdtrtGalleryUi.toggleExpanded($, $currentGallery, triggered);
    });
