marginnote adds spacing before paragraph

Question

Unwanted spacing

The marginnote package introduces some extra spacing between the section header and the start of a paragraph (this is unwanted). How can this be corrected?

Example

MWE

\documentclass{extarticle}

\usepackage{lipsum}
\usepackage{marginnote}
\usepackage{titlesec}

% Shorten the spacing after section headings
\titlespacing\subsection{0pt}{12pt plus 4pt minus 2pt}{0pt plus 2pt minus 2pt}

\begin{document}
\subsection{Normal spacing}
\lipsum[1-4]
\subsection{Unwanted spacing}
\marginnote{Something very long and interesting. Something very long and interesting.}
\lipsum[1]
\end{document}

Answer 1

This code with a simple \marginpar seems to improve the layout:

\documentclass{extarticle}

\usepackage{lipsum}
\usepackage{titlesec}

% Shorten the spacing after section headings
\titlespacing\subsection{0pt}{12pt plus 4pt minus 2pt}{0pt plus 2pt minus 2pt}

\begin{document}

\subsection{Normal spacing}
\lipsum[1-4]
\subsection{Unwanted spacing}
 \leavevmode\marginpar{\raggedright Something very long and interesting. Something very long and interesting.}
\lipsum[1]

\end{document}

Answer 2

Adding the \hrule makes the spacing more obvious. Evidently \marginnote adds a \strut at the beginning instead of a simple \leavevmode.

\documentclass{extarticle}

\usepackage{lipsum}
\usepackage{marginnote}
\usepackage{titlesec}

% Shorten the spacing after section headings
\titlespacing\subsection{0pt}{12pt plus 4pt minus 2pt}{0pt plus 2pt minus 2pt}

\begin{document}
\subsection{Normal spacing}
\lipsum[1-4]
\subsection{Unwanted spacing}
%\hrule
\smash{\marginnote{Something very long and interesting. Something very long and interesting.}}%
\lipsum[1]
\end{document}
