Really?
What browser are you using... as Chrome on my Mac seems to do just fine. Let me guess...FireFox?
The top line is another bug... that is known about.
It's definitely an issue with FireFox... since most other browsers do not suffer from it. Ultimately it should be FireFox that fixes it, as I seriously doubt that every other browser has an "issue" with it... but hopefully XF developers can enact a workaround for FireFox's apparently crappy coding.
