[NTG-context] markings in lmtx and luatex

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
