I expected, when pressing Ctrl+Q that it would drop the entire stack of items on the ground.

What actually happened was the stack of items instead was placed into my boots inventory slot. I tried again with the block still in the boots slot and it merely replaced the item that was already there.

Steps to Reproduce:
1. Place more than one block in your hotbar.
2. Highlight it and press Ctrl+Q
3. Item is placed in your boots.
