DnsRecord::queryRecords - SOA has an empty "target"

When I use queryRecords to retrieve a SOA record, the record is returned but has an undefined target.

stdClass Object
(
    [record_id] => 1
    [zone_id] => 1
    [domain] => example.com
    [type] => SOA
    [host] => example.com
    [target] => 
    [ttl] => 43200
    [last_update] => 0
)

The TinyDNS server is actually returning a SOA record for the domain, and it is defined in the InterWorx GUI. Shouldn’t I see a value returned by the the API, too?

Is this one still an issue?
