Changing Angry tag of aggressive wolves is not working

Hurt wolf

Trying to set the Angry tag of wolves you hit to 0b does not have any effect.

Joined wolf

There seems to a difference between a wolf that was directly hurt by the player and one that joined the attack (see also MC-94010).
When setting the Angry tag of joined wolves to 0b their texture changes to a peaceful one, however they are still attacking the player.
