Dear list,

In the MWE below, the line with
\setuphead[chapter][before={\blank[3*line,force]}] disrupts the grid
typesetting in the first page. What am I missing?


\setuplayout[grid=yes]
\showgrid
\setuphead[chapter][before={\blank[3*line,force]}]

\starttext

\startchapter[title={Chapter}]
\dorecurse{7}{\input tufte}
\stopchapter

\stoptext
