The backs of an aggravated enderman's eyes are visible when looking at it from behind or from the side

The backs of an aggro'd enderman's eyes are visible when looking at it from behind or from the side.

To reproduce

1. Go to the end

2. /execute as @n[type=enderman] at @s run damage @s 1 mob_attack by @n[type=enderman,distance=1..]

3. /tick freeze

4. Look at the aggro’d enderman’s head from below and from the side/behind it
   ❌ The backs of its eyes are visible

Expected result

The backs of its eyes would not be visible

Note

The best way to fix this is probably to add a roof to endermen’s mouths so that their heads do not appear hollow. (For context, the hollowness of villagers' heads being revealed under some circumstances was recently considered a valid bug (see MC-302919 - un-WAI’d but still not triaged), so the same logic should apply here.)
