This is a very interesting bug, failure in Safari 4.0.3 is caused by completely different reasons than in current ToT. The blank space comes from an iframe that's supposed to be resized after loading. JavaScript code that does this fails in shipping Safari/WebKit due to incorrect cross-domain security checks (the main frame and subframe come from news.naver.com and memo.news.naver.com respectively, but both set document.domain to naver.com). ToT fails because document.documentElement.scrollHeight returns a wrong result. Bug 25240 tracks issues such as this one. *** This bug has been marked as a duplicate of bug 25240 ***
