Comment 28 for bug 1934221

I've tested systemd 247.3-3ubuntu3.6 from hirsute-proposed in a VM and can verify it is working as expected.

I used the configuration provided and kept the VM running for several days without any crash:
```
root@hh-vm:~# cat /etc/systemd/resolved.conf
[Resolve]
DNS=46.182.19.48#dns2.digitalcourage.de 1.1.1.1#cloudflare-dns.com 9.9.9.9#dns.quad9.net
DNSSEC=yes
DNSOverTLS=true
MulticastDNS=no
LLMNR=no
Cache=no
DNSStubListener=yes
Domains=~.
root@hh-vm:~# dmesg | grep segfault
root@hh-vm:~# dmesg | grep "systemd-resolve"
root@hh-vm:~# resolvectl query google.com
google.com: 142.250.185.238 -- link: enp5s0
            2a00:1450:4001:813::200e -- link: enp5s0

-- Information acquired via protocol DNS in 121.0ms.
-- Data is authenticated: no
```

DNS requests are working as expected and I could not provoke a crash by disconnecting the network interface midway through a DNS request, forcing a timeout.
