Ray.TransformToRef doesn't normalize direction

Hi, I was debugging some code and stumbled upon Ray.TransformToRef and I noticed probably a bug?

The result ray's direction is never normalized unless I'm mistaken.

public static TransformToRef(ray: Ray, matrix: Matrix, result:Ray): void {
            
            Vector3.TransformCoordinatesToRef(ray.origin, matrix, result.origin);
            Vector3.TransformNormalToRef(ray.direction, matrix, result.direction);
            // This should be result.direction.normalize(); ? 
            ray.direction.normalize();
            
}
