ArticleFeedbackv5 uses a deprecated core module, jquery.appear. This should ideally be replaced with the non-deprecated core module mediawiki.viewport.
The instances of the jQuery module being used is in modules/jquery.articleFeedbackv5/jquery.articleFeedbackv5.js:
jquery.articleFeedbackv5.js (line 2144)
$.articleFeedbackv5.$holder.appear( function () { if ( !$.articleFeedbackv5.isLoaded ) { $.articleFeedbackv5.load( 'auto' ); // Track form impressions $.aftTrack.track( $.articleFeedbackv5.experiment() + '-' + 'impression' ); } } );
The method is also referenced in another comment:
jquery.articleFeedbackv5.js (line 2163)
// Adding hash in url will not scroll down to this id, because the element // won't exist until .appear is triggered. Let's just simulate this ourselves. if ( '#' + $el.attr( 'id' ) === window.location.hash ) { $.articleFeedbackv5.highlightForm(); }
