Large number of kernels are running for a single notebook

See original GitHub issue

Issue Type: Bug

I was editing a TypeScrip notebook, adding cells, moving things around, running cells. I ended up with 25 running kernels.

Thanks for the bug.

Do they go away after shutdown? This might happen if you opened a bunch of notebooks and didn’t close VS code.

It should also be noted you’re listing ports there. Each kernel running opens 5 ports. Each notebook being open runs two kernels. So just having two notebooks open would be 20 ports visible.

@kieferrm, can you still repro this? Don has not been able to on Mac.
