Hi everyone. The following example works fine with MkIV, but fails
with latest LMTX.

To be specific, the lam-alif ligature isn't working. Compile with both
to see differences.

Majalla is a Windows font, so I guess it's available for testing:


\mainlanguage[arabic]\definefontfeature
  [arabic]
  [mode=node,language=dflt,script=arab,
   init=yes,medi=yes,fina=yes,isol=yes,
   liga=yes,dlig=yes,rlig=yes,clig=yes,
   mark=yes,mkmk=yes,kern=yes,curs=yes]\definefontfamily[main][serif][sakkalmajalla][features=arabic]\setupbodyfont[main]\setupdirections[bidi=global]\starttext
أهلاً وسهلاً\stoptext

Is that a bug or are more features to be specified? Thank you in advance.

Jairo
