Firefox 4 Issue with answer's paginator style

edit

When there is a paginator block in the answers (i.e. lots of answers requiring multiple pages to display), the layout of the first answer is messed-up.

In both Chrome and IE, the paginator is on a line by itself. In Firefox 4.01, the paginator doesn't use up all the line. It shifts the answer to the right, and the answer overflows in CARight.
