When press a crafting recipe in the recipe book, an item in the same slot where you pressed it moves

Every time i pressed the flint and steel recipe, the recipe is shown on the crafting table. But the thing is, when i clicked a certain crafting recipe, it accidentally pressed an item behind the crafting book slot (and that is your inventory slot)
Plz remove this bug / features because it can make you throw your things after you're done crafting something (i can't make th attacment because there's a problem)
