It's definitely a behavior change, right? You have a user agent now where you did not before.

WebPageProxyWin.cpp is not upstreamed yet. This patch changes nothing at the moment.
In the futre, WebKit2 for Windows port and WebKitTestRunner for Windows port will be finished to implement.
Existing test case http/tests/navigation/useragent.php will covers this change.
