Naughty Attributes doesn't cooperate with a custom editor script, can it be fixed?

[darth-biomech]

I've snatched from the web this code that adds an extension for the editor to make Vector3 with a specific attribute to display a handle so that they could be edited visually in the scene view. However, I noticed that if this code is present in the project at all (Even if it isn't being assigned to MonoBehaviour) - it breaks many Naughty Attributes, specifically what I've noticed - Rollout and ReadOnly.

Could you please suggest what I need to change in this to make it compatible with the NA?

    public class DraggableHandleDraw : Editor
    {
        readonly GUIStyle style = new GUIStyle();

        void OnEnable()
        {
            style.fontStyle = FontStyle.Bold;
            style.normal.textColor = Color.white;
        }

        {
            SerializedProperty property = serializedObject.GetIterator();
            while (property.Next(true))
            {
                if (property.propertyType == SerializedPropertyType.Vector3)
                {
                    FieldInfo field = serializedObject.targetObject.GetType().GetField(property.name);
                    if (field == null)
                    {
                        continue;

                    if (draggablePoints.Length > 0 && propertyOwner)
                    {
                        bool isRelative = draggablePoints[0].relative;
                        Vector3 end;
                        if(isRelative)
                        {
                            end = propertyOwner.transform.InverseTransformPoint(

                                    propertyOwner.transform.TransformPoint(
                                        property.vector3Value), propertyOwner.transform.rotation));

                    }
                }
            }
        }
    }

Some folks helped me with it, and the issue was fixed by changing inheritance to NaughtyInspector, and replacing the original OnEnable() with

        protected override void OnEnable()
        {
            base.OnEnable();
            style.fontStyle = FontStyle.Bold;
            style.normal.textColor = Color.white;
        }
