GizmoType.InSelectionHierarchy not detected correctly when NotInSelectionHierarchy is defined

UPDATED: How to reproduce:
1. Open the attached project "GizmosSelectedInHeirachyTests.zip"
2. Open "TestGizmoBehaviourDrawer.cs"
3. Change DrawSelectedGizmosAttempt3 to :

    [DrawGizmo(GizmoType.NotInSelectionHierarchy)]
    static void DrawSelectedGizmosAttempt3(TestGizmoBehaviour target, GizmoType gizmoType)
    {
        DrawGizmosInternal(target);
    }

4. Open Assets/GizmoTest/Scenes/SampleScene.unity
5. Select "Main Camera" or "Directional Light"

Expected results: Gizmos are drawn for TestTarget
Actual results: Gizmo for TestTarget is not drawn.  Reparenting TestParent under camera and then selecting light will start drawing the cube. So it sometimes works correctly but not always.
