I investigated the issue and with the Experimental Screen Type the backpack is being equipped into the cosmetic accessories/accessories:chest slot on shift clicking, from there the WrappedTrinketInventory is not returning the backpack anymore with getItem, which is expected as the slot is for cosmetic accessories.

So the problem really is that the backpack gets shift clicked into the cosmetic accessories slot instead of the chest/back slot.
I have it setup so that with trinkets it's only allowed into the chest/back slot. Is there a way for me to block it from entering the accessories/accessories:chest slot?

Hmmm so I believe it may be better instead of restricting going to the slot to change the ordering of slots attempted to be equipped in to prevent this case from occurring as often without people understanding that its cosmetic only.
