No NTP was running.

What software told the kernel that there was going to be a leap second at the
end of the day?

I guess it was part of systemd?

Unless you explicitly install ntp, systemd runs an SNTP-like client to keep
the time increasing (say across reboots) and notify the kernel of pending
leap seconds.  In that circumstance one would expect to see ...59:59 twice.
