Handles.DotHandleCap ztest issue

I don't want to draw a dot when an object is in front of it. As you can see in this image: I can do this with Handles.DotCap and set Handles.zTest = CompareFunction.Less. The problem is Handles.DotCap is Obsolete. And when I try Handles.DotHandleCap ztest does not seem to work. So how can I solve this or is this a bug in unity?

 [CustomEditor(typeof(Test))]
 public class DotHandleTestEditor : Editor
 {
     protected virtual void OnSceneGUI()
     {
         Handles.zTest = CompareFunction.Less;
         Quaternion lookAtRot = Quaternion.LookRotation(Camera.current.transform.position);
         float size = HandleUtility.GetHandleSize(Vector3.zero);
 
         if (Handles.Button(Vector3.zero, lookAtRot, size * 0.05f, size * 0.07f, Handles.DotCap))
             Debug.Log("This one works fine");
 
         lookAtRot = Quaternion.LookRotation(new Vector3(20, 0, 0) - Camera.current.transform.position);
         if (Handles.Button(new Vector3(1,0,0), lookAtRot, size * 0.05f, size * 0.07f, Handles.DotHandleCap))
             Debug.Log("This one does not do what I want");
     }
 }
