Auto crafting permenantly deletes items if you pick up the items that is used in the recipe from the ground

Here is how to recreate the issue.

1) Be in survival mode.

2) Fill up all your inventory except 8 slots. These items should not include sand AND gunpowder.

3) Place a crafting table.

4) Throw one stack of gunpowder to the ground right next to the crafting table.

5) Get 4 stacks of sand and 4 stacks of gunpowder on the remaining inventory slots.

6) Go right next to the crafting table where you can pick up the gunpowder from the ground.

7) Use the crafting table and shift left-click to TNT recipe. It places items worth 51 TNT.

8) Shift left-click on the TNT again without crafting the previous 51. It tries to place 64 but fails and one stack of gunpowder is lost.
