Dear list,

I am facing a problem with grid alignment when using paragraphs. I think it could be a bug because the MWE below produces lines which are correctly aligned to the grid with the context version included in texlive 2017, but it does not seem to work with the context in texlive 2018 and the current beta (ConTeXt  ver: 2018.12.07 19:37 MKIV beta  fmt: 2018.12.14).
This is the MWE:

\setuplayout[grid=yes]
\defineparagraphs[twocols][n=2]
\showgrid

\starttext
\starttwocols
  \input knuth
\nexttwocols
  \input knuth
\stoptwocols
\stoptext

Am I doing anything wrong? If not, I'll appreciate any suggestion or workaround.

Thank you in advance for your help.
