breakable option and tcbdocmarginnote / tcolorbox inside of marginnote

[mkm-gh]

When using the breakable option in a margin note (tcbdocmarginnote or tcolorbox inside of marginnote) and the box is „pushed“ to a new page, the layout is broken. Please see the minimal example below.

This may be related to the known issues of the marginnote package.

\documentclass{article}

\usepackage{lipsum}

\usepackage{marginnote}

\usepackage[most]{tcolorbox}
%\usepackage[most,documentation]{tcolorbox}

\begin{document}

\lipsum[1-5]

%\clearpage % This dirty fix resolves the issue

\section{A}
Text
\marginnote{\begin{tcolorbox}[breakable] % breakable causes the problem
A
\end{tcolorbox}}
Text

% The following is also broken

%\section{A}
%Text
%\tcbdocmarginnote[breakable]{ % breakable causes the problem
%A
%}
%Text

\end{document}

According to package manual of marginnote, sec. 2 Issues Using marginnote:

No page break can occur within a margin note created using the \marginnote command.

So using breakable tcolorbox in \marginnote is meaningless. The broken layout may be caused by wrong detection of remaining page height triggered by breakable option.
