Crafting Cake/Honey Blocks activates a glitch state where crafting results are dropped on the ground instead of put in the inventory, and Anvils and Grindstones don't consume primary ingredients

In this bug, crafting a Cake or Honey Block will not work if there is an open hotbar slot— it will send the Bottles/Buckets into the same slot as where the Honey Block/Cake is supposed to be, thus causing the Honey Block/Cake to disappear, leaving only the secondary result of Bottles/Buckets and activating a "glitch state" (will get into this in the next paragraph). Crafting an item with a near-full inventory and an item on the ground will also activate this glitch state for a similar reason— if the item is picked up just as you receive the crafting result, one gets deleted because they both try to enter the same inventory slot.

Now onto the glitch state— this causes crafting in ANY crafting station (Crafting Table, Stonecutter, you name it) and also causes Grindstones and Anvils to not consume the item in the first slot, while also throwing the result on the ground, as seen in this video: https://youtu.be/2E3jPiizHAc

This, of course, creates an infinite duplication glitch for any item- putting a decent Enchanted Book in a Grindstone and spamming the result will grant loads of XP, which in turn can be used in an anvil to name any item to duplicate it.

I can confirm this works on Realms and in singleplayer. This has also consistently worked with multiple different iOS versions (all of my friends on different iOS versions have been successful in replicating the bug).
