Backport PR #42539 on branch 1.3.x (Revert "CI: runtime warning in npdev build")
Backport PR #42539: Revert "CI: runtime warning in npdev build"
Hmm. This actually xpasses on 3.8 npdev as well in addition to Python 3.9, hence the CI failure. Maybe the solution is to just remove the xfail altogether. Unfortunately, without #42538 backported, we won't know, since master has no 3.8 np dev job anymore.

I think we should wait on this one for a while. If a better solution comes up, we can always close this and backport that one. > Hmm.

you can also do a PR against the 1.3.x branch directly and see OK, this seems to also xpass on 3.8 npdev(1.3.x branch). I'll try to send in a PR soonish.
