Tamed wolves get angry at an armor stands after hitting it. They will not stop being angry and growling at it even after it has been broken.

What I expected to happen was....

The wolf would stop being angry at the armor stand after I destroy it.

What actually happened was....

The wolf was still angry and growling even after destroying it.

Steps to reproduce:

1. Tame a wolf
2. Place an armor stand
3. Attack it while being in survival mode
4. Destroy the armor stand
5. → The wolf will still be angry at the armor stand that doesn't exist
