It looks like this change may have caused the output in @vitest/ui to print ANSI escape codes.

I commented on #3582 but realized I should probably open a new issue:

It looks like something in #3582 may have caused the output in @vitest/ui to print ANSI escape codes.

I'm not sure what the root cause is, but I'm sure it started after I upgraded vitest this week.

Not sure if desirable, but you could use https://github.com/drudru/ansi_up to render ansi codes into HTML.

Isn't this a pretty serious bug? Is there something I'm doing that makes it happen to me, but not to others?

👀 I'm going to work on this issue, but I'm not sure how to test @vitest/ui :(

You can run test/core tests with --ui flag for example:

cd test/core
pnpm test --ui
