QWebSocketCorsAuthenticator always returns empty request origin

I have browser plugin that connects to my web socket (non ssl) written in Qt. I want to do some authentication based on origin of request. Correct way for this to handle originAuthenticationRequired signal. But QWebSocketCorsAuthenticator in the slot always returns empty origin.

My request is ( from chrome net internals )
--> GET / HTTP/1.1
Host: localhost:8080
Connection: Upgrade
Pragma: no-cache
Cache-Control: no-cache
Upgrade: websocket
Origin: chrome-extension://cedihnhifeohmckhgmabjajiblengcak
Sec-WebSocket-Version: 13
User-Agent: Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/40.0.2214.94 Safari/537.36
Accept-Encoding: gzip, deflate, sdch
Accept-Language: en-US,en;q=0.8
Sec-WebSocket-Key: ZyVXN1Xj1rjc1tgeddG8nQ==
Sec-WebSocket-Extensions: permessage-deflate; client_max_window_bits

Which has a non empty origin.

After some frustration, looked into Qt sources and found the problem in qwebsockethandshakerequest.cpp (line 263).

m_origin = m_headers.value(QStringLiteral("sec-websocket-origin"), QString());

It is not looking for "Origin" header at all.

Can we expect a fix in 5.4.1
