[NTG-context] blank line and signals

Hi all, please have a look at the following example: \newsignal\SectionSignal \def\TestSpace% {\relax\ifdim\lastskip=\SectionSignal \blank[nowhite] \else \blank \fi} \setuphead[section] [after=\blank\vskip\SectionSignal] \setuphead[subsection][before=\TestSpace] \starttext \startcolumns \section{Section} \subsection{Subsection} \dorecurse{50}{some text, } \stopcolumns \stoptext If one removes the blank line after \section{Section} the output is correct, otherwise \TestSpace is ignored … I'm quite sure it worked a couple of weeks before.
