[Pdns-users] Ignoring wildcard due to TXT record

after our migration from PowerDNS 2.9.21 to 3.1 we just noticed another 
unexpected behaviour. If a TXT record for a subdomain is defined, a 
wildcard at the same subdomain level is ignored.

Example (zone=domain.com):

whatever.domain.com TXT "some text"
*.domain.com A

Querying for whatever.domain.com with the type TXT correctly returns 
"some text". Querying for whatever.domain.com with the type A returned in 2.9.21, but returns just the SOA of domain.com in 3.1.

What is the reason to introduce this behaviour? I think BIND has the 
"bug", meaning that once an explicit subdomain is found, further 
wildcards are ignored, even they do have a different type. I was happy 
that earlier PowerDNS releases implemented it the way one would 
intuitivly expect.

Kind regards
