DNS A records returned when asking for AAAA

I have Tor v0.2.5.0-alpha-dev running with DNSPort 53

Tor incorrectly returns an A record when asking for an AAAA

$ host -t aaaa google.com 127.0.0.1
Using domain server:
Name: 127.0.0.1
Address: 127.0.0.1#53
Aliases: 

google.com has address 74.125.132.138

Additionally, if there is no AAAA record, it still returns an A

Using Google's public DNS:

$ host -t aaaa chase.com 8.8.8.8   
Using domain server:
Name: 8.8.8.8
Address: 8.8.8.8#53
Aliases: 

chase.com has no AAAA record

Using Tor's DNSPort

$ host -t aaaa chase.com 127.0.0.1  
Using domain server:
Name: 127.0.0.1
Address: 127.0.0.1#53
Aliases: 

chase.com has address 159.53.84.126
