Chrome on Linux does not use teredo IPv6?

What happened? It seems Chrome and Chromium on Linux don't use IPv6 if the IPv6 is provided by teredo / miredo.

Everything works in Firefox, Miredo, lynx, ping6, etc with ipv6.google.com.

It looks like Chromium does not do a IPv6 DNS lookup; if I use a literal IPv6 address, it still works in Chromium.

I'm quite sure it all worked earlier on. Is Chrome/Chromium going the Windows way, so "if teredo, do not lookup IPv6 addresses"?
