[NTG-context] Extra space in align if tagging is enabled

Hi, There is an extra vertical space after displayed formulas with align if pdftagging is enabled. If I remove the last \NR it goes away (but I have got the idea that one should have that final \NR there?) /Mikael \setuptagging[state=start] \starttext \samplefile{knuth} \startformula \startalign \NC A \NC = B\NR \stopalign \stopformula \samplefile{knuth} \startformula \startalign \NC A \NC = B \stopalign \stopformula \samplefile{knuth} \stoptext
