Bug Description

Distributor ID: Ubuntu
Description: Ubuntu 20.04.4 LTS
Release: 20.04
Codename: focal

systemd 245 (245.4-4ubuntu3.16)
+PAM +AUDIT +SELINUX +IMA +APPARMOR +SMACK +SYSVINIT +UTMP +LIBCRYPTSETUP +GCRYPT +GNUTLS +ACL +XZ +LZ4 +SECCOMP +BLKID +ELFUTILS +KMOD +IDN2 -IDN +PCRE2 default-hierarchy=hybrid

When I execute:
sudo resolvectl domain neth0 ~example.com example.com
I expect:
Link 17 (neth0): ~example.com example.com

As per man:
"domain [LINK [DOMAIN...]] - The domain command expects valid DNS domains, possibly prefixed with "~", and configures a per-interface search or route-only domain."

What I get instead is:
sudo resolvectl domain neth0 ~example.com example.com

/etc/resolv.conf -> /run/systemd/resolve/stub-resolv.conf
contains search example.com

resolvectl domain neth0
Link 17 (neth0): example.com

And:
sudo resolvectl domain neth0 example.com ~example.com

/etc/resolv.conf -> /run/systemd/resolve/stub-resolv.conf
contains no search line

resolvectl domain neth0
Link 17 (neth0): ~example.com
