BASIC01 does not find parent domain when testing an .arpa-domain

[repperille]

When starting a normal test with the .arpa-domain
0.0.9.0.0.0.7.0.1.0.0.2.ip6.arpa
the test fails in BASIC01 with B01_NO_CHILD even though it is a sone

$ dig soa 0.0.9.0.0.0.7.0.1.0.0.2.ip6.arpa

The same error (B01_NO_CHILD) happens when testing the parent zone
0.0.7.0.1.0.0.2.ip6.arpa

But it works when testing the parent of the parent!

Something is in error when Zonemaster cannot find the parent zone in this case:

Hi @repperille,

Thanks for the feedback!

I can confirm that this is a bug in the implementation. It has been identified and we will provide a fix.
