Vertical alignment problems with marginnote and titlesec

Question

I'm with a document that has margin notes in the section titles. I have programmed a command that works if I don't load titlesec package. Here is a minimal example:

\documentclass[a4,twoside]{article}
\usepackage[spanish]{babel}
\usepackage{blindtext}
\usepackage{changepage}
\usepackage{marginnote}
\usepackage{calc}

% \usepackage{titlesec} % No titlesec crap, works

\setlength{\parindent}{0pt} 
\newcommand{\margen}[2][0pt]{%
  \marginnote{%
    \normalfont\footnotesize
    \checkoddpage    
    \ifoddpage {\parbox[t]{\marginparwidth}{\raggedright{\normalfont\footnotesize#2\normalfont}}}
    \else      {\parbox[t]{\marginparwidth}{\raggedleft{\normalfont\footnotesize#2\normalfont}}}
    \fi
  }[#1]
}


\newlength\altura
\setlength{\altura}{\heightof{{\Large C}}}
%\setlength{\altura}{\heightof{{C}}}
%\setlength{\altura}{0pt}

\begin{document}
\section[Uno]{One\marginnote{Test text}}

\blindtext[1]

\section[Dos]{Two \margen{Another secion note}}
\blindtext[1]

\section[Tres]{Three\margen{\blindtext}}%

\blindtext[2]

\section[Four]%
%{Four \margen[-\altura]{Fourth note \\and a little more text}} %  One of the tests modifying the height.
% With the configuration of this file, it does not work.
{Four \margen{Fourth note \\and a little more text}}
\blindtext[1]

\end{document}

The problem is that when I activate titlesec, an extra vertical space appears, I don't know where it comes from. I've been testing with marginnote's loading parameters, but it means having to insert vertical elements for the correct alignment. Another solution I was considering, is to force a vertical movement, but I can't find a convenient way to know the size of the extra space included in titlesec.

I would be happy to receive any solution, suggestion or hint to solve this.

Best regards.

Edit:

This is the correct alignment form:

And this is the wrong way, when titlesec is loaded:

Answer 1

With titlesec you need to raise by the \baselineskip.

\documentclass[a4paper,twoside]{article}
\usepackage[spanish]{babel}
\usepackage{changepage}
\usepackage{marginnote}
\usepackage{calc}

\usepackage{titlesec} % No titlesec crap, works

\usepackage{lipsum}

\newcommand{\margen}[2][0pt]{%
  \marginnote{%
    \normalfont\footnotesize
    \checkoddpage    
    \parbox[t]{\marginparwidth}{%
      \ifoddpage\raggedright\else\raggedleft\fi#2%
    }%
  }[\dimeval{#1-\baselineskip}]
}

\begin{document}

\section[Uno]{\margen{Test text}One}

\lipsum[1]

\section[Dos]{\margen{Another secion note}Two}
\lipsum[1]

\section[Tres]{Three\margen{\lipsum[3][1-2]}}%

\lipsum[2-3]

\section[Four]%
{Four \margen{Fourth note \\and a little more text}}
With the configuration of this file, it does not work.
\lipsum[1]

\end{document}

I simplified the code. Of course, the margin notes go in the outer margin.
