i dunno, but i remember problems with splits between chapter, section and
subsection heads and context prohibits that; *any* tex where some construct
introduces whitespace has this problem but i can imagine some tricky stuff with
the otr involved (and even then there may be interference with preceding
material); i do (did) observe that latex has a different spacing model (and
interfering penalties may be a reason why sometimes spacing gets messed up);
i will implement a second spacing model once luatex is available
in tex, when one has a controlled situation, solutions are possible but context
is rather configurable
\setuphead[section][after=\blank\pelanty10000\relax] may help but also mess up
spacing
(esp floats are hard to interface with such things because they also look at
the available space and currently don't look back; keep in mind that when
looking back the content is already put in the mlv and ther ei sno knowledg
ewhat is preceding the current structure
