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

I've seen a few issues on GitHub & StackOverflow without code examples to reproduce this issue so I went ahead an created a barebones repo to help uncover the root of this problem.

Thanks for the repo.
You seem to be piggy backing on the node debug adapter as far as I see -> forwarding to @roblourens
@lukebarton what debug adapter stop events are you sending in this example?

I don't know enough about debugging to know the answer to your question. The debugger is launched via vscode with the included launch config (.vscode/launch.json), the breakpoint is set in the editor and I halted the debugger via the vscode debug toolbar.

It's worth pointing out, which may not have been clear from my gif, but if you reintroduce the linebreak I deleted, the debugger will fail again. The presence of the line seems to cause it to fail. I haven't investigated whether it's blank lines, total line count, or what.

I don't know why this is just an issue recently, maybe some change in Jest
