It looks like the first instance of this failure was on 11/20 at r270137, though that commit doesn't seem related at all, so it must have been something near that.

I reverted https://trac.webkit.org/changeset/270132/webkit in https://trac.webkit.org/changeset/270311 because it caused flakiness in an API test on macOS, perhaps that could be related.
