OK. We'll just have to live with it for the moment then (Iʼm not about
to propose to people that they switch off TLS1.3 support, since
they'll forget to turn it back on).
Amusingly I only see it because itʼs triggered by
network-security-level > medium, which must change some timing
somewhere (adding logging or running nsm non-byte-compiled makes it go
away).
