To the best of my knowledge, this implementation of mDNS on IPv6 is not actually tested. Its implementation may be incomplete.
Did you try to enable it ?

After some nights of pulling my hair I'd say it's broken. If anyone are interested in continue my work I could share my findings. I'll leave my branch as is.

#9330 enables the IPv6 side of the mDNS responder: it answers AAAA questions and announces the IPv6 addresses (and services) over ff02::fb, so
<host>.localresolves to the ESP's IPv6 address. The query side (MDNS_IP6_SUPPORT) is still off, so this is a partial fix, but it covers the common case of finding the device over IPv6. Tested on several ESP8266 devices with ESPHome.
