Hraban,
From what I understand, the marginal is an insert attached to a line,
and |\placesidebyside| is a vertical block; without a reliable line
anchor, ConTeXt pushes it away. A solution? Either force a line anchor
(|\dontleavehmode ... \par|), or (better) encapsulate |\placesidebyside|
in a box and apply a |voffset| calculated on |\ht| of the box (so the
marginal follows the block, even if it jumps from page to page). I don't
know if the following MWE is the most elegant or effective (or robust)
approach, but it seems to work (at least for me, the test is functional,
even though I haven't tested it beyond two pages). I don't know if
that's really the goal you're looking for either...You'll tell me !

Hi,
if I call a marginal before a \placesidebyside (don’t know how to call
that more generally), it gets placed only at the bottom, and sometimes
on the next page (couldn’t reproduce that in the MWE).
If I use the voffset option, I can move it up, but only manually,
since I don’t know the height of the following construct – in my book,
that’s a code example beside the result. And voffset doesn’t help if
the marginal moved to the next page.
Do you have a solution?
