[NTG-context] extra nattab split in columns

Hi, there occurs extra page break when natural tables is in the columns: ------------------------------------ \showframe \starttext \startcolumns Text. \bTABLE[split=yes] \dorecurse{100}{\bTR\bTD line\eTD\eTR} \eTABLE \stopcolumns \stoptext ------------------------------------ I do not know why there is extra \page \bgroup\page\egroup inside of \splittblboxa (core-ntb). Box breaking should be implicit here (we are not inside a float here since \splittblbox forks this), should not? Commenting mentioned line(s) solves this special problem. Not understanding all background I do not know if it causes some unwanted side-effect. Vit
