A duplication trick after you try to craft honeyblocks or cake.

Hello. I am here to report a but that my friends and I discovered on our realm. I have also been able to do the bug in single player. What happens is you try to craft an item that gives you an item back along with the newly crafted item. An example is crafting a honey block and getting bottles with it. We would try to craft honey blocks or cakes and the honey block / cake would appear in our inventory but then be quickly replaced by the bottles / buckets. After this happened, whatever you crafted would pop out of your inventory onto the floor immediately. You could duplicate things by using an anvil or a grindstone, the final product of both would be crafted then popped out, and the. everything will be replaced except for exp. I hope this gets fixed soon because I like playing minecraft without the ability to cheat. Please and thank you.
