Hello experts,

I am stumped trying to eliminate the extra vertical space in the following example. Can anybody point out where it is coming from and, more importantly, how to eliminate it. All lines should be on the grid, but the paragraphs environment clearly is introducing extra space (or removing it). I do note that the problem exists with MkIV and LMTX not giving the same result, but with neither setting on the grid.

\setuplayout     [grid=on]
\showgrid
\defineparagraphs[TwoCols]
                 [n=2]
 \setupparagraphs[TwoCols]
                 [each]
                 [before=\blank[line],after=\blank[line],
                 ]
 \setupparagraphs[TwoCols]
                 [2]
                 [width=.6\textwidth]
\starttext
\input dawkins\par
\input dawkins\par
\startTwoCols abc\nextTwoCols abc\stopTwoCols
\startTwoCols abc\nextTwoCols abc\stopTwoCols
\startTwoCols abc\nextTwoCols abc\stopTwoCols
\input dawkins
\stoptext
