hand_inv containers do not reopen with the player's inventory when closed

1. Equip any item with a hand_inv container, like Walter's Slingshot. This will show a hand_inv slot above the Slingshot.
2. Open a Wardrobe, or anything else that closes the inventory bar.
3. Observe that the hand_inv slot that should be present above the Slingshot is no longer present.

It should be noted that the container still functions while closed, it simply cannot be interacted with by the player until the item is reequipped.
