        * html5lib/resources/webkit01.dat: Added the demo case for the new code. Added a case that exposes crash when not using hasTagName().
        * html5lib/runner-expected.txt: Since the behavior of InForeignContentMode has changed, the expectations need to be updated. These have been manually verified.
        * platform/chromium/html5lib/runner-expected.txt: Ditto.
        * platform/win/html5lib/runner-expected.txt: Ditto.
