jQuery update required

The shortcode prints the following code:
<script>jQuery(window).load(function(){jQuery(".feed_dynamic_classlhwjxixrdq_page").masonry({itemSelector: ".fts-jal-single-fb-post"});});</script>
Please update to
<script>jQuery(window).on('load', function(){jQuery(".feed_dynamic_classlhwjxixrdq_page").masonry({itemSelector: ".fts-jal-single-fb-post"});});</script> for jQuery 3 compatibility (without the jQuery migration file, it would show a JS error).
