The bug
Enderman will make the stare sound whenever they turn hostile towards the player, even if the player didn't stare at it. (it was already fixed once in MC-88209).
This doesn't however affect Endermen becoming hostile towards Endermites or Iron Golems.
How to reproduce
Find an enderman (or spawn one)
Hit it while looking at its feet
→ It makes the stare sound while attacking
