[pstricks] nodes connection outside a psframebox

[cédric ody]

Dear pstricks users,

I am linking nodes with ncangle connections inside a psmatrix environment,
inside a psframebox.

However, the connections are not taken into account in the calculation of
the framebox and the connections go outside the framebox.

Here is the code:

\documentclass{article}
\usepackage{pstricks}
\usepackage{pstricks-add}

\begin{document}

\begin{figure}[p]
\psframebox[linearc=0.5,cornersize=absolute]{
  \begin{psmatrix}[rowsep=2.,colsep=2.]
      [name=H] A & & [name=WW] B \\
    & [name=WW2H] C & \\
  \end{psmatrix}

  \ncangle[angleA=270,angleB=270]{->}{H}{WW2H} \ncput*[npos=0.5]{1}
}
\end{figure}
\end{document}

Any hint,

cedo
