1 year ago I think I discovered the origin of this 'behavior':
as soon as I added a file .env containing the WiFi credentials of the WiFi AP to be connected,
the unwanted CPY statusbar lines in between the REPL output of the running script disappeared. See below:
soft reboot
Auto-reload is on. Simply save files over USB to run them or enter REPL to disable.

Description
There is no need for more detailed description. See the REPL output under 'Behavior' and you can see what happens.
Note: This script depends on the following files: feathers3.py boot.py secrets.py
Additional information
What I think should not be is: CircuitPython statusbar lines in between the REPL output of the running script.
This never saw this happen before. I don't like this to happen. I think: during the execution of a script one should only see the REPL output of that script. After ending the script it is OK to see the CPY statusbar again.
I had this 'experience' also the past days on other boards running CircuitPython V8..0.0-beta.3. At first I didn't want to report this 'phenomena'. Instead I used a file
boot.pytoHowever, I think such a drastic measure shouldn't be necessary.
