There's a bug that deletes your items on the new Crafter

I putted an item on the slot at the right where the crafted result shows up on the ui of the crafter and it deleted my item, in creative and survival modes.

What I expected to happen was...:
I thought it wouldn't do anything, like with a normal crafting bench or an anvil, you just can't put items there

What actually happened was...:
The item got deleted, then I tried with another item and it happened the same, then I tried on survival and it happened the same

Steps to Reproduce:
1. Place the new Crafter table onto any block (I did onto an iron block I don't know if that affects it, and the Crafter was facing west)
2. Enter the crafter ui
3. Place an item on the slot where the results should show up, the crafter for me was empty and I placed a glass block
