Leaked debug processes on VS Code reload window

[kieferrm]

Issue Type: Bug

1. enable experimental debugging
2. open a notebook
3. run a cell line-by-line (or use full debugging - doesn't matter)
4. while debugging is running reload window
   -> debug process is still hanging around

I ran this in a codespace.

When I run the same steps but using the js debugger, no process leaks.
