Text adjustment of first incorrect when not signed in

Hi. Refering to this post.

When I'm logged in, it looks fine. But when I'm not logged inthe first line is not correct lined up to the next lower line. So far I have only seen this behaviour in that spesific post.

The attached image shows how it look like in Firefox 23. It does look the same in Opera (not logged in).

You are running an ad blocker that is blanking out an advert. This is creating the blank area.

I thaught so too, but it apear the same both in Firefox and Opera.
