Works fine for me here on 3.10.  5857::129 is the SNAT box

09:33:34.664987 IP6 5858::200.57294 > 5854::1.53: 24043+ [1au] A? ibm.com. (36)
09:33:34.665060 IP6 5857::129.57294 > 5854::1.53: 24043+ [1au] A? ibm.com. (36)
09:33:34.666017 IP6 5854::1.53 > 5857::129.57294: 24043 1/4/5 A 129.42.38.1
(226)
09:33:34.666044 IP6 5854::1.53 > 5858::200.57294: 24043 1/4/5 A 129.42.38.1
(226)

and conntrack output:

udp      17 28 src=5858::200 dst=5854::1 sport=40687 dport=53 src=5854::1
dst=5857::129 sport=53 dport=40687 mark=0 use=1

Suggest doing some tcpdumps to see where your packets are going.  And also
confirming the UDP service is actually responding to v6 packets.
