When carrying an item in hands that can't be placed in inventory (eg jerry can, 2nd rifle), when an item is used that forces the carried item to leave the hands, the carried item disappears permanently. It does not reappear where it originally spawned.

Carry an item in hands that doesn't fit in inventory.
Use another item that needs to occupy hands when used.
This is a new version of an existing problem, previously the carried item might have appeared in the inventory or reverted to where it spawned. In (experimental) 0.53.126370 it now just disappears.
