When I'm in crafting table to duplicate a banner pattern, I accidentally put an item in crafting table with the shift key, and it consumed my item (in my case it was dirt)
What I expected to happen was...:
When I put the dirt, I expected that the craft will not work.
What actually happened was...:
Instead, the craft continues working and it even consumes a dirt per banner duplicated
Steps to Reproduce:
1. Make a custom banner and try to duplicate it with putting it in a crafting table with a same colored banner
2. Put another item in the craft
3. Take the loot and it will consume the other item.
