False positive in S3966: calls to arg.Dispose() are not handled correctly

[sm-g]

public static class Test
    {
        public static void CloseRabbitConnections(IConnection connection, IModel channel)
        {
            channel.Dispose();
            connection.Dispose(); // this line - S3966	Refactor this code to make sure 'Test' is disposed only once.
        }
    }
