VS Code cannot cancel test

[ThierryOyhanto]

Does this issue occur when all extensions are disabled?: Yes

• VS Code Version: 1.100.2
• OS Version: Windows 11 Pro 23H2

Steps to Reproduce:

1. Create new folder and open it with vs code
2. create virtualenv .env (Python 3.9)
3. activate .env and pip install pytest
4. create test file test_cancelTests.py
5. add following code

import time

def test_tests():
    time.sleep(1000)
    pass

7. select Python Interpreter .env
8. configure test for Pytest
9. execute test in test explorer
10. Cancel test with "Cancel Test" button

Result : python process still running 1000s
Expected : python process must exit or killed

Note : With "Python Test Explorer for Visual Studio" extension, python process exit when "Cancel Test" was pressed

(.env) C:\Temp\BUGVSCODE>pip list
