Dragon Egg Dup

This is Dragon Egg Dup. Under the portal placed 9 prismarine wall. Dig a hole 6-7 blocks high above the portal. Puts Dragon Egg and it starts to fall. When it fell to the end, we wait a bit and go into the portal. Now we see an egg that teleported naturally, and an egg that dropped from the prismarine wall and teleported to the end. I hope you fix this terrible bug. Thanks.
