That's weird because I just tried a small test here which worked just
fine.  Can you send a _really_ _minimal_ reproducible case that I can
use to diagnose the problem?

I would have said, "Pass an FxObjectWrap* instead of an FxObject* to
pythonHandle", but my test seemed to prove that it wasn't
neccessary... and that matches my expectations since pointer
to-python conversions are supposed to undergo automatic downcasting
for polymorphic types.
