WebKit is using libsoup's WebSocket implementation. Prior to releasing
2.68.0, I made sure that libsoup's websockets pass all autobahn tests.
There were a couple of tests that were failing due to issues similar to
what you describe. Additionally, Carlos Garcia made several fixes to
libsoup to get all webkit websocket tests to pass, so it might just be
a matter of upgrading to at least 2.68. Could you try and see if you
can still reproduce the issue with that or a newer version of libsoup?
