Regardless of the use of the interface in the DNS Resolver configuration, it's restarted at every rc.newwanip event

It should be restarted only if the interface is used in the configuration of the DNS Resolver (in/out interface)

FreeBSD 12.3-STABLE

DNS resolver still restarts after every "rc.newwanip" no matter whether the interface is selected in the configuration of the DNS Resolver (in/out interface).

I selected only the LAN interface as DNS Resolver (in/out interface).

# Interface IP(s) to bind to
interface: 192.168.20.1

# Outgoing interfaces to be used
outgoing-interface: 192.168.20.1

After, rc.newwanip event on the WAN:

Jun 3 08:52:40     check_reload_status     399     rc.newwanip starting vtnet0

Unbound rebooted. 

Jun 3 08:52:40     unbound     30541     [30541:0] info: service stopped (unbound 1.15.0).

The code looks like it should be right but we can debug it for the next release, it's not a blocker for 22.05.

It seems the problem is back in 2.7.0 - even if nothing has changed running rc.newwanip is restarting unbound.
