Short Description:

When using the crafter to dispense items into a container (IE chest, barrel, dropper, etc.) like you can do with a dropper, it only works with empty containers, and does not work when trying to dispense into non-empty containers.

Explanation:
When you try to use the crafter to dispense something into an empty container, it works properly just as the dropper does, and puts the item in that container. However, if you are dispensing into a non-empty container, it will just spit out the item in item form, where as the dropper will just not dispense at all.

Since it has been said multiple times that the crafters should be expected to work like droppers, this can cause confusion for someone new to redstone, could cause more lag (now you have more item entities), and it is just inconsistent with other redstone.

Final Info:
I have attached a Image showing the result of trying to do this, and you can see the items that got spat out by the crafter, and not the dropper. I also attached a video, so that you can see this happening in game.

I really hope this bug gets fixed before the full release, because I and many others are really excited to use this new block the second the update comes out. Thanks for looking into it
