Clothing Sprites Disappear when in Backpack or Other Storage Item

[nodesc]

Description of issue

Certain clothing sprites that are worn in the uniform slot have their sprites not render correctly when placed into a storage item like a backpack. This makes them difficult to remove and in some events, impossible as they cannot be detected properly, leading to a large chunk of space taken up by an item that cannot be removed. This only seems to occur when the uniform item has things attached to it. Normal baggy pants would render fine in a container, but would fail to render if a suit jacket was attached to it.

Difference between expected and actual behavior

Seeing how the sprites render when equipped in the Uniform slot, and in the two hand slots, I feel like the sprites should also render when placed into a backpack or other storage item.

Steps to reproduce

(How I did it)

1. I equipped baggy pants with a suit jacket and a necklace attached in my character loadout. (Depending on the role. Jobs with have loadout items in the suit slot tend to attach the items automatically, while ones that don't will have them equipped separately in different slots.)
2. I unequipped the uniform and placed it in my backpack (which in this scenario was tailbags, but also worked when placed in a red toolbox.)
3. The sprite would not render when in the container.

Possibly related to #4652

Leaving or entering an equipment slot appears to clear the overlays.

Proccalling update_icon() refreshes the overlays and fixes the issue.

Appears to happen whenever equipped() is called. Not consistent. This is weird.
