Manage Versions page inconsistent across browsers

There are some inconsistencies in the manage versions page across browsers.

In Firefox, the versions table borders are gray, whereas in Internet Explorer 7.0, the borders are white. In Internet Explorer 7.0, the version description font size seems to take a default font size, making it larger than the rest of the fonts in the same table. Check both IE anf FF screenshots to see the differences.

I though that the issue could be related to JRA-10955, but when testing in 4.0.0 Milestone 1, the Internet Explorer page did not change. FireFox did change the table cell borders to white. Personally, I think white borders make the table less readable.
