\emph not working in LMTX (bug?)

The following crashes with LMTX (current version: 2020.08.03 14:25):


\starttext
\emph{Hola}
\stoptext

Log:


\emphasiscorrection ->\ifhmode \ifnum \currentgrouptype =\aligngroupcode

\else \expandafter \expandafter \expandafter \font_emphasis_look \fi \fi

<to be read again> \egroup

\egroup

l.2 \emph{Hola}

Is it a bug? \emph worked for older versions. Thank you in advance.

Regards,

Jairo

Yes and it was already reported by Pablo but don't hesitate report 
future bugs.

The following worked some days ago. Now it crashes:

\setuphead[chapter][alternative=middle,textstyle=\cap,numbercommand=\WORDS]
\setuphead[section][sectionsegments=section,align=middle,textstyle={\bf},conversion=R,numbercommand={\bf}]
\setuphead[subsection][numbercommand=,textstyle={\it},sectionsegments=subsection,conversion=n]
\starttext
\startchapter[title=Dummy chapter]
\startsection[title=Dummy section]
\startsubsection[title=Dummy subsection]
\input knuth
\stopsubsection
\stopsection
\stopchapter
\stoptext

The log says:

\endgroup

\fakeheadnumbercontent \fi \begstrut \headtextcontent

\endstrut }

I guess it's unrelated to Pablo's issue (\emph works again after the patch).

This caused by the second related problem mentioned in my answer, you 
get the error message for the \cap and \WORDS command.

In this case there is a easy fix and also better chapter setup:

\setuphead
   [chapter]
   [alternative=middle,
    textstyle=cap,
    numberstyle=WORD]

Indeed. I really appreciate the fast testing of context lmtx updates 
because that way we can move on fast and in steps.

There was a file missing in the lmtx setup.

New upload. I pruned some 15 year old stub code (from the early luatex 
dev times, it was still around; probably more such old code can go), so 
hopefully all generates well.

Happy testing,

Hans
