[NTG-context] LMTX deeptextcommand issue

Dear All,

my document ends with the index

\startbackmatter
\chapter{Rejstřík jmenný}
\start
\switchtobodyfont[8pt]
\placeindexname
\stop
\stopbackmatter
\startbackmatter
\chapter{Rejstřík věcný}
\start
\switchtobodyfont[8pt]
\placeindexsubject
\stop
\stopbackmatter

At the beginning there is a condition for one word (kind of manual column
balancing) - but according to the log, see below, this seems to be an issue:
\newconditional\IndexState
\define[1]\IndexInternalCommand
 
{\doifelse{#1}{Dolsko}{\global\settrue\IndexState}{\global\setfalse\IndexSta
te}#1}

\define[1]\IndexCommand
  {\setfalse\IndexState
   \setbox\scratchbox\hbox{#1}%
   \ifconditional\IndexState
     \column
   \fi
   \box\nextbox}

\defineregister[indexname][indexnames]
\setupregister[indexname][command=\Word, textcommand=\IndexCommand,
deeptextcommand=\IndexInternalCommand]

\defineregister[indexsubject][indexsubjects]
\setupregister[indexsubject][command=\Word]
\setupheadtext[indexname=Rejstřík jmenný]
\setupheadtext[indexsubject=Rejstřík věcný]


This worked in luatex 1.0.1, but in LMTX I am getting:

When I've seen that 'crap' and weird page dimensions, I thought it is part
of the April fool, like all that LMTX announcement.

This issue is not urgent, I was just curious how different the output is.

Thanks,

Jan
