When using node coordinates in a matrix of nodes in the article document class, the following code works well and soes exactly what it is supopsed to:

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{matrix}
\begin{document}
\begin{tikzpicture}
   \matrix (m) [matrix of nodes]
   {
   A & B & C\\
   D & E & F\\
   };
   \draw (m-1-1)--(m-2-3);
\end{tikzpicture}
\end{document}

If I try to get the same result in beamer by doing

\documentclass{beamer}
\usepackage{tikz}
\usetikzlibrary{matrix}
\begin{document}
\begin{frame}
   \begin{tikzpicture}
      \matrix (m) [matrix of nodes]
      {
      A \& B \& C\\
      D \& E \& F\\
      };
      \draw (m-1-1)--(m-2-3);
   \end{tikzpicture}
\end{frame}
\end{document}

compilation fails with 

Package pgf Error: No shape named m-2-3 is known.

Using a fragile frame makes no difference. Is there a way to make the node names in a matrix of nodes work in beamer?
