O ambiente Itemize tem recuo errado em uma legenda suspensa?

Question

Quero usar o ambiente itemize dentro de uma legenda suspensa, mas o recuo é igual ao do corpo principal. Gostaria que a listagem fosse recuada da legenda suspensa.

\documentclass{scrbook}
\usepackage{caption}

\begin{document}
foo foo foo foo foo foo foo foo foo foo foo foo 
foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo
foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo 
foo foo foo foo foo foo foo foo foo foo foo foo foo foo 
\begin{itemize}
    \item bar
\end{itemize}

\begin{figure}
\captionsetup{singlelinecheck=off}
\caption[foo bar]{foo foo foo foo foo foo foo foo foo foo foo foo 
    foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo
  \begin{itemize}
       \item this listing belongs to the caption
       \item but looks as if it was part of the body
  \end{itemize}}
\end{figure}

\end{document}

Parece provável que tal configuração possa ser uma exclusão e não a norma. Portanto, defina os itens manualmente usando \textbulletum espaçamento apropriado itemize.

\documentclass{scrbook}

\usepackage{caption}

\begin{document}

foo foo foo foo foo foo foo foo foo foo foo foo 
foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo
foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo 
foo foo foo foo foo foo foo foo foo foo foo foo foo foo 

\begin{itemize}
  \item bar
\end{itemize}

\begin{figure}
  \captionsetup{singlelinecheck=off}
  \caption[foo bar]{foo foo foo foo foo foo foo foo foo foo foo foo 
    foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo

    \textbullet \hspace{\labelsep}this listing belongs to the caption

    \textbullet \hspace{\labelsep}but looks as if it was part of the body
  }
\end{figure}

\end{document}

Você também pode definir o conteúdo em um tabularxambiente:

\documentclass{scrbook}

\usepackage{caption,tabularx}

\begin{document}

foo foo foo foo foo foo foo foo foo foo foo foo 
foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo
foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo 
foo foo foo foo foo foo foo foo foo foo foo foo foo foo 

\begin{itemize}
  \item bar
\end{itemize}

\begin{figure}
  \captionsetup{singlelinecheck=off}
  \caption[foo bar]{foo foo foo foo foo foo foo foo foo foo foo foo 
    foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo

    \medskip

    \noindent
    \begin{tabularx}{\linewidth}{@{\phantom{\figurename~\thefigure:~}} l @{\hspace{\labelsep}} X @{}}
      \textbullet & this listing belongs to the caption \\
      \textbullet & but looks as if it was part of the body
    \end{tabularx}}
\end{figure}

\end{document}
