Tamed wolves which are angry at creakings remain angry when said creakings despawn

When a tamed wolf attacks a creaking, if the creaking disappears at dawn at this point, the tamed wolf that has lost its hate target will continue to act angrily for a while.

How to reproduce:

1. Place a creaking heart between two correctly aligned pale oak logs.
2. Summon a wolf and tame it.
3. Creaking attacks Creaking after spawning, and makes sure that tamed wolves start attacking Creaking.
4. Execute any of the following commands or wait until dawn:

   /time set 23300
   /time set day

1. When the creaking spawns, attack it and let your wolf attack it as well.
2. Keep attacking the creaking yourself to make sure your wolf will remain angry at it.
3. Wait for the creaking to despawn.
   → The wolf is still growling.

Expected result:

A tamed wolf would stop being angry at a creaking when it despawns.

Observed result:

A tamed wolf remains angry at a creaking even after it despawns.
