[NTG-context] columnset vs columns

Minimal example: \definepapersize[PaperSize][ width=400mm, height=100mm, ] \setuppapersize[PaperSize] \starttext \startcolumnset[n=3] \dorecurse{3}{\input knuth} \stopcolumnset \stoptext The old-columnsets module fails with an error. The following works as expected: \definepapersize[PaperSize][ width=400mm, height=100mm, ] \setuppapersize[PaperSize] \starttext \startcolumns[n=3] \dorecurse{3}{\input knuth} \stopcolumns \stoptext Thank you.
