Block Duplication Glitch

I found this bug that occurred whenever a villager has recently slept in a bed. I went in my world to sleep in my bed that was in a village in a village house, and I saw a nitwit villager sleeping inside. So I broke the bed and he got out of my house.

Then I went to place my bed and when I placed it, I saw it on the ground for a split second! Then it just disappeared! So I went to another villager's house and as I was walking to go sleep in the bed there, I started holding the right mouse button to eat some bread, when all of a sudden my bed just.. APPEARED right in front of me! I was really confused and picked up my bed again back to my house and decided to move my crafting table. I picked up the crafting table and brought it to another location when I tried to place it down and it just disappeared like the bed! I went over to right click because I thought it would appear on the ground again and it did! So I went to get another villager's bed to put next to the crafting table but when I tried to place it down on the ground... It placed a CRAFTING TABLE! Super weird!

 

I tried this with another bed and it ALSO placed down 2 beds when I tried to place down my furnace. I don't know how this bug got in the game but it's kind of cheating to duplicate valuable blocks.

 

I also tried it again with another bed and it ALSO placed 2. But like I said in the beginning it only works with beds that a villager has just slept in. And it worked with other blocks because it just starts with a bed, then as it works it's way up it just gets weirder and weirder! I think this bug is very strange! Probably one of the strangest!
