Unable to place individual items one at a time in a chest or furnace without the entire stack.

When trying to place an individual item one at a time in a chest or furnace instead of the entire stack.

*When opening a chest to place an item or a portion of a stack inside I can't without the entire stack going in. Same with a furnace if I wanted to divide a stack of Iron for smelting in 4 furnaces I can't without placing full stacks of 64 in the drop box.

Steps to Reproduce:
1. Open the furnace to smelt something.
2. Try to divide items to smelt in multiple furnaces.
3. You can't without putting full stack
