Witches do not display head-equipped blocks

If a block is equipped on a witch’s head, it will be invisible. This is blatantly inconsistent with all other villager-shaped mobs.

Run this command: /summon witch ~ ~ ~ {equipment:{head:{id:carved_pumpkin}}}

Run the same command with “witch” replaced with one of the following: villager, wandering_trader, zombie_villager, vindicator, evoker, pillager, illusioner

Expected results would be for the pumpkin to be visible on witches. This does not happen.
