Public bug reported:

To verify:
1. Connect to a Wifi network that assigns IPv6 addresses.
2. Open http://whatsmyipv6.org/ note down the address.
3. Connect to a VPN.
4. Open http://whatsmyipv6.org/ and compare with the result from step 2.

Temporary fix:
Set the "Method" dropdown under "IPv6 Settings" in your Wifi connection to "Ignore".

I consider this a security bug since it endangers users relying on a
working/leak-free VPN.
