Embarassing. I must have not recompiled the tests after tweaking it.
Sorry for the oversight. I will deal with it.

Reproduces for me locally:

[pid   507] setsockopt(4, SOL_IPV6, IPV6_HOPOPTS, NULL, 0) = 0
[pid   507] recvfrom(3, 0x55fcf63813a0, 65535, 0, NULL, NULL) = -1 EAGAIN (Resource temporarily unavailable)
