A failed test has no relation with changed docstrings:

The test is known to be flaky on the backport branches, for some reason (I think @JelleZijlstra was having trouble with it recently). Not sure that anybody's worked out what the problem is, though.

@AlexWaygood A non-reverting fix (#91680) got merged so I've updated this PR. Update: Ubuntu tests now pass.
