Hi Joseph,

I think this is related to the fact that your paragraphs are hard to
break between pages, since they only contain two lines.

I think this paragraph break among pages is what triggers the issue you
mention.

https://live.contextgarden.net/ includes both LuaTeX 2.06 20200630 +
ConTeXt MkIV 2020.06.30 17:30.

Because the text fits in a single page.

Because you avoid the problem of breaking the paragraph between pages.

You can also avoid that using the following (but it will work only with
your MWE, I know):

  \setuplayout[setups=*lessstrict]
  \startsetups[*lessstrict]
      \widowpenalty=1000
      \clubpenalty=1000
      \brokenpenalty=1000
  \stopsetups

  \setuplayout[setups={*lessstrict}]

  \showgrid

I think that the problem might be related to the (unsuccesful) avoidance
of orphans and widows in current latest.

But of course, Hans or Wolfgang know better.

Just in case it might help,

Pablo
