Thanks for your PR. Not for endgame, will review once I am back from vacation in 2 weeks

This looks good.
@flurmbo in order to merge this in can you please:

1. resolve the confilicts
2. test that it works in latest
3. write unit tests that cover your case. Here's a pointer https://github.com/Microsoft/vscode/blob/f6caa53cdd87f3fcee7de78d6a5b60a6835cde29/src/vs/workbench/contrib/debug/test/browser/debugANSIHandling.test.ts#L1

@isidorn sure I'll try to get to it in the next few days!

[flurmbo]

Hey @isidorn I made the changes you asked for, let me know what you think!

[isidorn]

Thanks a lot. This week we are in endgame which means we only bugfix and take limited changes. Due to that I am assigning this to march and I will probably review next week.

@flurmbo great work, merging this in. Nice tests
Thanks a lot!
