I have discovered a work around. Tailscale manually overwrite /etc/resolv.conf to do dns resolution when it is unable to correctly interface with systemd-resolved. This is the default behavior on most distros bundled with NetworkManager & systemd-resolved. To allow Tailscale to properly communicate, follow the instructions here
