[NTG-context] markings in lmtx and luatex

[Thomas A. Schmitz]

Hi all,

something has changed in the way markings are handled. Consider the 
following example:

\definemarking[Section]

\setupheadertexts[{\getmarking[Section][top]–\getmarking[Section][bottom]}]

\starttext

A\marking[Section]{A}

B\marking[Section]{B}

C\marking[Section]{C}

\page

D\marking[Section]{D}

E\marking[Section]{E}

F\marking[Section]{F}

\page

G\marking[Section]{G}

H\marking[Section]{H}

I\marking[Section]{I}

\stoptext

Compiled with luatex, the result is not quite as expected, but at least 
it goes into the right direction. Compiled with lmtx, "top" and "bottom" 
are always identical. Something appears to be amiss here.

Best wishes

Thomas
