[Tkinter] macOS Catalina and Python menu issue

[chrstphrchvz]

I don't have a solution, but the issue described here sounds identical to an upstream Tk issue on macOS Catalina, which I reported a few months ago, but is still unresolved due to difficulty reproducing the issue or finding a working solution for it.

Please see the upstream ticket and add a comment if you're interested in getting updates or possibly helping to investigate it: https://core.tcl-lang.org/tk/tktview?name=bf93d098d7
