[issue38946] IDLE on macOS 10.15 Catalina does not open double-clicked files if app already launched

If it's helpful, I'd be happy to do a screenshare session (Google Meet, Zoom, etc), to demonstrate and explore the behavior.

We have a 10.15.4 Mac with python 3.8.3 freshly installed from python.org, Tk version 8.6.8, IDLE version 3.8.3. IDLE file opening functions very differently on this machine then on any Linux or Windows machine I've used in the past decade.
