SerializationVersion           1.1.0.1

Steps to reproduce

  1. Open PowerShell or PowerShell Core in Windows Terminal
  2. Simulate blocking behavior with Python command:
    python -c "import time; import threading; t = threading.Thread(None, lambda: time.sleep(9999)); t.start(); t.join()"
  3. Press keyboard shortcut Ctrl+Break

Expected behavior

Terminated Python process

Actual behavior

Python process is still running

Additional notes:

I tried the same steps in pure PowerShell (powershell.exe)/PowerShell Core (pwsh.exe)/CMD (cmd.exe) - and the result is terminated Python process.
