#Tailscale dns resolution through userspace socks5 proxy

Currently, on a Linux host, when running in userspace networking, Tailscale doesn't seem to resolve magicdns entries, such as when using ALL_PROXY=socks5h://localhost:1055 curl magicdnsentry.

Is there an expected way for this to work?

#

Specifically, I want tailscale 4via6 routing to work via dns entry, but it currently only works with the raw IP:

And same result when ALL_PROXY=socks5://localhost:1055 instead
