[XeTeX] \addtokomafont{footnotereference}{} doesn't work with xltxtra package

[Marcel Stadelmann]

Hi,

The Komascript order to define the format and the font of a  
footnotemark is ignored, as soon as the xltxtra package is loaded.  
Somebody has an idea for a workaround?

\documentclass{scrartcl}
\usepackage[xetex,table]{xcolor} 			
\usepackage{fontspec}
%\usepackage[no-sscript]{xltxtra}
\usepackage{etex}
\usepackage{xunicode} 					

\addtokomafont{footnotereference}{\sffamily\color{blue}}

\begin{document}
\rmfamily
Ein Minimalbeispiel\footnote{Test}
\end{document}

Best regards
Marcel
