When dropping a magazine directly on an equipped item, for example a pistol, the magazine is not removed from the proximity inventory

Steps to reproduce:

• Have an unloaded pistol equipped
• Stand next to some furniture that has a magazine in it
• Use the inventory window to drag the magazine directly onto the equipped item
• Watch the pistol be reloaded and the magazine staying inside the furniture you're standing next to.
