I'm working on both Mac and PC with a test for which is current,
so using the correct button depending.
I know I've got that part right because I get pop-ups everywhere
else I expect/need them, just not in the tree.
I'm going to do some more testing as another review of the code,
and an attempt to mirror your simple test, shows that it's still
not working as I would expect, BUT the problem could lie in
some wrapper code that exists between the treeview and the
parent window.
I'll post a follow-up if I can't get things to work.

Thanks, I appreciate the situation and will try to get a bug
report filed with them.
