Created new world in snapshot 19w03b as survival with cheats on.  Put myself in Creative to build new composter with hopper to chest.  Tried various items in the composter.  Put myself back in Survial, went out and picked kelp.  Tried to use the crafting table for dried kelp.  It would allow the recipie to place the kelp for me as many times as I wanted, but would not produce the dried kelp.

What I expected to happen was...:
I expected to craft dried kelp

What actually happened was...:
no dried kelp was produced in the crafting table and the kelp was returned to me

Steps to Reproduce:
1. Be in Survivor mode
2. Collect Kelp
3. Use the recipie book to place kelp into crafting table.

4. Click in result block to try to get dried kelp (nothing shows)
