In case of bug report: Expected behaviour you didn't see

IPv6 nameservers should be removed from /etc/resolv.conf when changing the wifi network. This works for IPv4.

IPv6 nameservers remained in /etc/resolv.conf after change of wifi network. IPv4 nameservers were purged.

1. Connect to IPv6 capable wifi network 1
2. Receive IPv6 nameservers via RDNSS option in RADV
3. Connect to wifi network 2
4. Receive IPv6 nameservers via RDNSS again
