Trouble with fallthrough

[zamadatix]

Hey there, I'm having some trouble getting the fallthrough to actually fallthrough. With "test1.example.com" in the local zonefile and "test2.example.com" in netbox I'm getting the following behavior:

Giventhe Corefile:

#    netbox {
#        token MyTokenHere
#        url http://10.20.30.40/api/ipam/ip-addresses
#        fallthrough
#    }

    file /etc/coredns/example.com
}

Queries to test1.example.com resolve and test2.example.com fail. Given the Corefile:

    netbox {
        token MyTokenHere
        url http://10.20.30.40/api/ipam/ip-addresses
        fallthrough
    }

#    file /etc/coredns/example.com
}

Queries to test1.example.com fail and test2.example.com resolve. Given the Corefile:

    netbox {
        token MyTokenHere
        url http://10.20.30.40/api/ipam/ip-addresses
        fallthrough
    }

    file /etc/coredns/example.com
}

Queriest to test1.example.com still fail and test2.example.com resolve. I'm not quite sure why fallthrough isn't letting the file's answer resolve. One thing I thought is maybe I have the plugin position wrong but it's before "file:file":

And even trying it at the very end of the list or very beginning of the list isn't changing the behavior.
