These two tests crash when run under WebKitTestRunner - but not DRT - on both Mac and Windows.
I cannot reproduce those crashes on WebKit2 EFL (tests are passing too). Could you please check if you still experience the crashes? Maybe we can unskip them now.
I cannot reproduce those crashes either on Mountain Lion with WKTR. I am going to unskip those tests.
