Deferring or JS Async breaks your UI

Hi, I just want to find out if you already have a fixed on this issue. I’m currently optimizing our websites and I’m applying the suggestions given by gtmetrix and pagespeed insights, which is to defer js and css. However, upon defering js and jquery, your plugin started to break and I saw on chrome’s console that one of the jquery ui plugins (jquery tabs) that you are using is the culprit (I think it stopped working because jquery has been deferred/async). If you can replicate this issue and hopefully would get back to me asap, it would be very much appreciated. Many Thanks.
