In the last beta, 'tlig' font feature doesn't work with 'mode=node'
anymore, that is I can't use it with Arabic:

\definefontfeature[default][default][mode=node]
\usetypescript[palatino]
\setupbodyfont[palatino]
\starttext
- -- ---
\stoptext

I'm not sure since when it was broken, but it has been working few betas
ago.

Regards,
 Khaled
