Thorns enchantment damage doesn't make target turn red

[uzilei]

Describe the bug
So the thorns enchantment does deal damage to the attacker, but does not turn them red (I hope you know what I mean by turning red)

To Reproduce

1. Get armour with thorns enchantment on it
2. Make someone or some mob to attack you
3. The damage is dealt, the attacker takes knockback and all the stuff like that, except for turning red

Expected behavior
Attacker turns red for about half a second just as if it has been attacked

Screenshots / Videos
Will get soon, I'm actually able to record this
