Comment (by DrMikeTwiddle):

 '''Update received from  from Little Snitch developer:'''

 According to the description of the user the mDNSResponder itself cached
 the address so I would assume this issue is about a leak between the Tor
 Browser and the mDNSResponder.

 Therefore it could be that the address was also listed in the Little
 Snitch Network Monitor for the mDNSResponder process.

 Little Snitch itself reads the DNS Cache from the mDNSResponder but does
 not trigger lookups by its own and does not read the local packets.

 Best regards,
 Simon

 He also mentions the URL presented here earlier (albeit with Safari):
