Reverts #12039

Seems like the CI has been failing since #12039. Providing a quick fix for this might not be very trivial, and therefore I am opening this PR to revert the change.

LGTM thanks! just fyi to skip GitHub Actions jobs as well as Jenkins [skip ci] needs to be on the commit message subject too (its already been going for a while so we can wait it out or you can update, either is fine). also can you comment on #12039 once this is merged?

Thanks for the advice! Already referenced the PR but will also leave a comment after merge.

I'm sorry, it may be because that the #12039 would change scheduled TIR to equivalent form, a set of updated meta-schedule cases check TIR structural equality failed.
