[NTG-context] Markings do not appear inside section block environments

Hello, The following lines do display the markings: \definemarking[M] \marking[M]{Cool} \setupheadertexts[{Marking: \getmarking[M]}][{Marking: \getmarking[M]}] \starttext Hello world! \stoptext but if I use a section block environment they do not: \definemarking[M] \marking[M]{Cool} \setupheadertexts[{Marking: \getmarking[M]}][{Marking: \getmarking[M]}] \starttext \startbodymatter Hello world! \stopbodymatter \stoptext How can I get markings working inside section block environments?
