Inventory items held by mouse cursor are dropped in the world

When you are in any inventory (user inventory, chest, furnace, etc.) and have items attached to the mouse cursor while closing the inventory, then these items are dropped in the world. This is not what I would expect to happen. I didn't throw them out, but rather more likely I failed to click on the spot where they were supposed to go before closing the inventory. I feel like the items should stay in the spot where they were grabbed by the mouse instead of throwing them in the world.

This could very well be the intended action, but I still wanted to address this issue.
