Description

In the IDE v. 1.8.19 running on MS Windows 10, serial monitor doesn't reconnect after Uno R4 board reset:
using Uno R3 and analog read example (analogRead + Serial.println), output continues after board reset.

Using R4 minima, it stops and serial monitor needs to be closed and opened again to get serial output.

On the other hand, IDE v.2 displays "Not connected" for a while and then continues to display output after board reset.

Research direction

Reproduce the issue in Arduino IDE 1.8.19 on Windows 10 with an Uno R4 Minima running the analogRead and Serial.println example. Compare the serial monitor behavior after a board reset with an Uno R3 and IDE 2; done means output resumes automatically without closing and reopening the monitor.
