[NTG-context] grid + section in text -> unwanted vertical space

Dear list, With the following example: \setuplayout[grid=yes] \setuphead[section][alternative=text] \starttext \section{Test}\input knuth \stoptext I get the attached result. I would expect no "empty line" between the section line and the rest of the paragraph. Any advices? Best regards, Mikael PS Using an updated MKIV
