<http://trac.webkit.org/r111416> caused fast/dom/prototype-inheritance-2.html to fail in Mac WebKit2, and, according to bug 80696 comment 59, also GTK and Qt.
This is not port-specific at all.
Updated the Mac expected results for this test in <http://trac.webkit.org/r111466>.
I'll skip it in GTK.
I have figured out the reason for failing test. I no sure why bot didn't catch this.
