Fixes #9542 . It took me about an hour to fix the issue, and another 4 to figure out why the baselines were dropping files for the test changes 😩 (see comment on changes in
projectsRunner.ts).I'm still verifying the changes to a couple of existing baselines are correct, but wanted to get this out for review now.
