When the execution hits document.open() (Document::open(Document* ownerDocument)), with WebKit2 the frame is in FrameStateProvisional state, while with WebKit, it is in FrameStateComplete state. 313951 1 74916 zalan 2010-11-26 04:20:30 -0800 Created attachment 74916 test case 314304 2 zalan 2010-11-29 01:30:19 -0800 got fixed with https://bugs.webkit.org/show_bug.cgi?id=49605 Committed r72122: http://trac.webkit.org/changeset/72122 74916 2010-11-26 04:20:30 -0800 2010-11-26 04:20:30 -0800 test case newwin.html text/html 697 zalan PGh0bWw+IAo8aGVhZD4gCjx0aXRsZT5KYXZhU2NyaXB0IFdpbmRvdyBPcGVuIC8gQ2xvc2UgVGVz dCAxPC90aXRsZT4gCjwvaGVhZD4gCjxzY3JpcHQgdHlwZT0idGV4dC9qYXZhc2NyaXB0Ij4gCnZh ciBuZXdXaW47CmZ1bmN0aW9uIGNyZWF0ZVdpbmRvdygpIHsKbmV3V2luID0gd2luZG93Lm9wZW4o IiIsICJhd2luIik7Cm5ld1dpbi5kb2N1bWVudC5vcGVuKCk7Cm5ld1dpbi5kb2N1bWVudC5jbG9z ZSgpOwp9CiAKZnVuY3Rpb24gY2xvc2VXaW5kb3coKSB7CmlmIChuZXdXaW4pIHsKICBuZXdXaW4u Y2xvc2UoKTsKICBuZXdXaW4gPSB2b2lkKDApOwp9IGVsc2UgewogIGFsZXJ0KCdXaW5kb3cgYWxy ZWFkeSBjbG9zZWQnKTsKfQp9Cjwvc2NyaXB0PiAKPGJvZHk+IAogCjxwPiBDbGljayB0aGUgIm9w ZW4gcG9wdXAgd2luZG93Ii4KIAo8cD4gRXhwZWN0ZWQ6IHdpbmRvdyBvcGVucyBhbmQgbm8gbG9h ZCBwcm9ncmVzcyBpcyB2aXNpYmxlLgogCjxwPiBCdWc6IHdpbmRvdyBvcGVucyBidXQgbG9hZCBw cm9ncmVzcyBpbmRpY2F0b3IgaXMgdmlzaWJsZS4KIAo8cD48YSBocmVmPSJqYXZhc2NyaXB0OmNy ZWF0ZVdpbmRvdygpOyI+T3BlbiBQb3B1cCBXaW5kb3c8L2E+IAogCjxwPjxhIGhyZWY9ImphdmFz Y3JpcHQ6Y2xvc2VXaW5kb3coKTsiPkNsb3NlIHRoZSBQb3B1cCBXaW5kb3c8L2E+IAogCjwvYm9k eT4gCjwvaHRtbD4gCg==
