Steps to Reproduce:

1. Connect with Remote - SSH to Linux and create a .py

import time
breakpoint()
if __name__ == '__main__':
    x = 1
    while True:
        x += 1
        print(x)
        time.sleep(1)

2. Use the command "Python Debugger: Debug Python File"
3. Right click the Call Stack and choose Copy Call Stack
4. Actual output to clipboard: <module> (\home\vmware\foo.py:3)
