There was a problem hiding this comment.
Nice! My only nit would be to break up the large test file for readability but that's not a blocker.

I see what you mean, but that was intentional. Regexes that are too greedy might come up again, and long test snippets are more likely to include examples that trigger these bugs. |

Fixes #3480.
We had a few regexes of the form
/^(some prefix)(?:\r?\n|\r)(?:[\s\S]*(?:\r?\n|\r))??\1$/m. This is incorrect as the greedy[\s\S]*will overrun all occurrences of the captured prefix until the last occurrence is found. I replaced it with/^(some prefix)$[\s\S]*?^\1$/m.
