Beacon Duplication Glitch

This is a really bad bug. This needs to be fixed ASAP. This is a duplication glitch/bug which can duplicate literally anything. When you open the beacon interface and you quickly double click any item in the first row of your inventory, it will duplicate. You can duplicate anything absolutely anything except unstackables. This is really bad bug/glitch. The upside is very less people knows about this but as soon as people knows it they will exploit it.(We too exploited it in one of our servers but later we deleted that world). I will attach a video of it as well as I'll drop an unlisted video link for youtube. Please fix this at priority.

 

Due to file size limit I can't upload the video but I'll upload the world and paste the video link.
