Tested with WebKit r20267. The page's content is blanked by mousing over the page's left-hand site index.
In Safari 420+ the page content is not effected. However, Safari 420+ is not displaying the pop-up menu that is intended by the mouse-over event.
Correct handling of the popup menu is seen in (at least) FireFox 2 and MSIE for Mac.
Bug is present with WebKit-CVS-2005-12-31 08-50-50 GMT.dmg.

Added some cases; commented out some that are irrelevant here and may even be not worth it trying to match. All the results are from WinIE 6.
I'm not working on a fix now, feel free to take this bug.
I'm working on this.
Alexey's test uncovers a lot of interesting little differences. The key to this site seems to be how we treat the empty string, though.

Fixes the empty string case, and the website.
I've broken off bug 13112 to cover cases other than the empty string. I didn't want to make those sorts of changes right now, though, because they're pretty risky -- especially when it comes to Dashboard.
