Item display with display set to head does not face the same direction as equipped on an entity

When an item display has the NBT item_display set to "head", it takes the head display settings properly. The problem is that this item is actually facing the wrong direction compared to a player/mob/armor stand that has the item in their head slot.

Steps to reproduce:

1. /summon armor_stand ~ ~ ~ {ArmorItems:[{},{},{},{id:furnace,Count:1}]}

2. /summon item_display ~ ~1.4 ~ {item:{id:furnace,Count:1},item_display:head}

3. Enable hitboxes with F3+B

Expected result

Both items would have the furnace front facing the same direction.

Actual result
The furnace front is on the opposite side for the item display.
