[NTG-context] orphans and widows not working in LMTX?

[Pablo Rodriguez]

Dear list,

I have the following sample:

    \showframe\showgrid
    \setuppapersize[A7]
    \setuplayout[setups=*lessstrict]
    \startsetups[*lessstrict]
        \widowpenalty=1000
        \clubpenalty=1000
        \brokenpenalty=1000
    \stopsetups
    \setupbodyfont[15pt]
    \starttext
    \dorecurse{5}{a\\
    b\\
    c\\
    d\par}
    \stoptext

Compiling it with current latest in LMTX (2020.08.07 23:37) leaves an
orphan line on page 2 (page #2 starts with "d").

MkIV beta from 2020.01.30 14:13 moves the the last line to avoid the
orphan (page #2 starts with "c").

Could anyone confirm the issue with orphans/widows in LMTX?

Many thanks for your help,

Pablo
