It's often that when I submit a PR, and the code runs through github ci, it will fail -- https://github.com/go-chi/chi/actions

I have to re-run the jobs to have it pass, it seems to be a timing issue. When running locally, it seems to work well pretty consistently, but I've seen the rare failing case.
