[luatex] Some ligatures Romande ADF Style Std not shown

[Pander]

Hi all,

The following

\documentclass{article}
\usepackage{xltxtra}
\begin{document}
also for the DemiBold for Romande ADF Style Std\\
\fontspec{Romande ADF Style
Std}\addfontfeatures{Ligatures={Required,Common,Rare}}
\noindent AE OE \char"E001 \char"E002 ae ff ffi ffl fi fl oe st ß\\
\end{document}

will result in both LuaLaTeX and XeLaTeX in a PDF with some ligatures
missing although these ligatures are available in the font.

This was reported against latest TeX Live on Ubuntu. Can someone
reproduce this? Can this be fixed?

Best regards,

Pander
