@j-f1 need fix bugs

Do you want to try to fix all the idempotency issues here or figure out a way to ignore them and make an issue about it?

I don't think we can fix all issues here. I've opened #7745 and #7746 , we can

1. fix the failed tests first then enable this test
2. ignore them and fix later

How about gating the reformat test behind an env variable, then only enabling it for one run? (i.e. create a new job that only runs on Node 13 in dev mode and tests the second format) You could set its continue-on-error attribute to true so CI will still be green.

I think better to add an option to run_spec to disable this check for specific tests, like I did with the disableBabelTS option.

We have filename, we can just simply list those failed files, and fix them later.

I'm AFK now, feel free to take over.

@j-f1 I can't request review from this PR, so friendly ping.

Oh, wow. Having tests for second format is going to be so good! 👏
