Bug GetAssetDependencyHash can't detect change on ScriptableObject

Unity version : 2020.3.30f1c1 and 2019.4.31f1

how to reproduce
1.Prepare a ScriptableObject （test.asset）
2.Get test.asset Dependency Hash
3.Add a new serialize field on the class
4.Get test.asset Dependency Hash
step2 and step4 hashes are same.

If I change the class's base class to MonoBehaviour, and use prefab to serialize data. Reproduce these steps, I can get diffirent hashes.So I think it's a bug.

I'm trying to implement an incremental asset build pipeline. I get runtime error which ask me to rebuild assetbundle of some ScriptableObjects recently.

 

Help~
