"Do you want to terminate the active terminal session?" on close for background terminals

Type: Bug

Behaviour

Popup on close: "Do you want to terminate the active terminal session?" even though none are running

Steps to reproduce:

2. Make sure Jedi is running, for example, lint a Python script
3. Try to exit VSC window

I did an extension bisect to pin down the Python extension as causing the problem.

I'm using Codium and I'm not sure if this issue affects Code.
