When you log out and back in, wolves stop being angry but still have red eyes

When I was playing Survival I was being attacked by wolves and when I logged out to update I found the wolves non-aggressive but still red-eyed, I have tested it out a little and in all game modes the same thing happens

To Reproduce:
1 - Aggro a wolf by attacking it
2 - Log out
3 - Log back in
and ta da, all angry wolves will now be non aggressive but still red-eyed
