Unity editor search functionality not working for sub class

Unity version 2020.1 added the ability to serialize generics in the inspector which is great.
However, when using this the Unity editor search functionality can't find the scriptableobjects that should show up.

Code (CSharp):

1. using System;
2. using UnityEngine;
3.  
4. [Serializable]
5. public class Distance<T> : ScriptableObject
6. {
7.     [SerializeField] private T _testVariable;
8. }
9.  
10. [CreateAssetMenu(menuName = "Distance", fileName = "DistanceSO")]
11. public class Distance : Distance<Vector3> { }

Code (CSharp):

1. using UnityEngine;
2.  
3. public class DistanceSerialize : MonoBehaviour
4. {
5.     [SerializeField] private Distance<Vector3> distance;
6. }

As you can see in the image, The unity search functionality doesn't find my DistanceSO and DistanceSO1 objects.

Is this a bug or something that will be added/fixed?
