This TLD messes up HN's title: "top-level domain representing the Occupied Palestinian Territory | Hacker News .فلسطين" I assume this is because Arabic is right-to-left, but it's interesting that only the title is affected.
Edit: This affects Mobile Safari on an iPad (iOS 5.1.1).
Displays correctly in FF 17 / Ubuntu 12.04, but only when Firefox is windowed. When maximised, the Unity bar takes over and I see the same bug you're seeing.
