The behavior of Chromium causes https://bugs.webkit.org/show_bug.cgi?id=55643 (Chromium unnecessarily creates SVGImage when an SVG document contains images).

Assuming WebKit's KURL behavior is correct, my first patch is to change KURLGoogle.cpp to match KURL.cpp, which affects the result of fast/url/relative.html. platform/chromium/fast/url/relative-expected.txt contains all PASSs, while fast/url/relative-expected.txt contains 8 expected FAILs, 2 of which relate to my question:

I don't know if KURL's behavior is correct, but I believe Chromium's behavior of resolving to an empty string URL in this case is not matched by any other browser. So I am pretty sure KURLGoogle is incorrect.

Adam made the test expectations all have PASS matching google-url behavior, without analysis of what is actually correct. I think it may be misleading for the tests to say PASS/FAIL at all at this point, but I would say the test should be rebaselined.
