We actually used to have an open preview event in addition to close
preview. An open preview event would solve this problem, since you
could populate your menu in response to that event.
Why was it removed? Would it be a good idea to reintroduce it? I still
kind of feel like I should be able to use a MenuHandler to populate my
Menu, that was my first attempt, because it seemed logical and in line
with everything else :)
This is not a big issue for me, I can live with a workaround for now,
but it would be nice for "completeness".
