Cannot bootstrap over IPv6

Using the current public TorBrowser build, I cannot connect to the Tor network from some machines.

torbrowser error dialog:

Tor failed to establish a Tor network connection.

Connecting to a relay directory failed (no route to host - 199.254.238.52:443).

Two of the addresses attempted here actually belong to hosts that have IPv6 connectivity: https://gist.github.com/sdstrowes/9e5cf5a3f2fe48ef3979 These hosts have the correct ports open and are listening, but TorBrowser doesn't try to connect. It's not always the case that hosts at this stage have IPv6, but at least some do.

References to 127.0.0.0/8 smells v4-specific, which isn't useful without IPv4 end-to-end. NAT64 won't help in this instance.
