I got round to having another look at this this afternoon.
(I'm using Catalina.) The workaround above does work for me,
though it seems like a pretty nasty one.

I tried the various reshufflings of the code suggested in various bugs,
stack-overflow questions, etc, about where we should call setActivationPolicy,
create menus, call activateIgnoringOtherApps, etc, but they didn't help.
