Vindicators, evokers and illusioners do not render items on head

The bug

If summon villager and vindicator with objects on the head, then the object will be visible only from the villager.

/summon villager ~ ~ ~ {ArmorItems:[{},{},{},{id:"minecraft:stone",Count:1b}]}

/summon vindicator ~ ~ ~ {ArmorItems:[{},{},{},{id:"minecraft:stone",Count:1b}]}

Although both the villager and the vindicator have almost the same model.
