Beamer with Berlin theme: slide in "hidden" section appears in navigation bar

Question

I am trying to achieve the same thing as in this question but using the Berlin theme, namely, I want to have a "Conclusion" slide at the end that does not appear in the top navigation panel.

By putting it in an empty-titled section as per the accepted answer I have succeeded in making it not appear as an additional slide in the last section. However, when the "Conclusion" slide is displayed, the navigation button to the first slide of the last section is highlighted (but the name of the section isn't). I would like to stop it, so that nothing in the top panel is highlighted when the "Conclusion" slide is displayed.

\documentclass{beamer}

\usetheme{Berlin}

\begin{document}

    \begin{frame}
        \titlepage
    \end{frame}

    \begin{frame}{Introduction}
    \end{frame}

    \begin{frame}{Outline}
        \tableofcontents[pausesections]
    \end{frame}

    \section{Context}
    \begin{frame}{Context}
    \end{frame}

    \section{Development}
    \begin{frame}{Development}
    \end{frame}

    \section{Results}
    \begin{frame}{Results}
    \end{frame}
    \begin{frame}{More results}
    \end{frame}

    \section{}
    \begin{frame}{Conclusion}
    \end{frame}

\end{document}
