I tested the patch inside a ubuntu focal vm and can verify that the bug is fixed.

Testing that has been done:
Enable proposed repository and install dnsmasq version 2.80-1.1ubuntu1.6:

cat <<EOF >/etc/apt/sources.list.d/ubuntu-$(lsb_release -cs)-proposed.list
# Enable Ubuntu proposed archive
deb http://archive.ubuntu.com/ubuntu/ $(lsb_release -cs)-proposed restricted main multiverse universe
EOF

apt update

apt install dnsmasq=2.80-1.1ubuntu1.6

dpkg -l | grep dnsmasq
ii dnsmasq 2.80-1.1ubuntu1.6 all Small caching DNS proxy and DHCP/TFTP server
ii dnsmasq-base 2.80-1.1ubuntu1.6 amd64 Small caching DNS proxy and DHCP/TFTP server

Stop systemd-resolved and start dnsmasq:
systemctl stop systemd-resolved.service
dnsmasq --server 8.8.8.8

Run the reproducer mentioned in this bug report:
for i in srv txt aaaa a aaaa a txt srv; do host -t $i test.foo. 127.0.0.1 | tail -n 1; done
Host test.foo. not found: 3(NXDOMAIN)
Host test.foo. not found: 3(NXDOMAIN)
Host test.foo. not found: 3(NXDOMAIN)
Host test.foo. not found: 3(NXDOMAIN)
Host test.foo. not found: 3(NXDOMAIN)
Host test.foo. not found: 3(NXDOMAIN)
Host test.foo. not found: 3(NXDOMAIN)
Host test.foo. not found: 3(NXDOMAIN)

All records are resolved with NXDOMAIN which shows the bug is fixed.

Thanks for the help and work Andreas and Miriam!
