Using IPv6 nameserver does not work: "dial udp6: lookup <ip6-addr>: no such host"

IPv6 support seems to be broken in 1.0.5:

$doggo --debug -6 www.cloudflare.com @2606:4700:4700::1111 
time=2024-10-16T21:14:18.752+02:00 level=DEBUG msg="LoadNameservers: Initial nameservers" nameservers=[2606:4700:4700::1111]

This happens with both a self-compiled and the prebuilt binary on Linux 6.11.4 (amd64).
My IPv6 support works otherwise.

At first glance it seems that the address parser seems to have a problem with the compressed IPv6 form, but expanding the address does not help:

$doggo --debug -6 www.cloudflare.com @2606:4700:4700:0:0:0:0:1111

The last element is consistently cut off.
