### Details

**Description**  
When dragging out items from players inventories, armor has a chance to be replaced by the item taken out.

**Steps to reproduce**  
Open another players inventory using /invsee
Drag items out of their inventory (I specifically chose 3 stacks of dirt). Shift clicking the item won't reproduce it.
Keep attempting to take away the dirt blocks and placing them back in (this entire time don't shift click anything)

**Expected behavior**  
Not replace players armor piece with the block taken away.
