When I mouse-over the featured tabs on both Stack Overflow main and here on Meta, the height of the box around the number seems to change. It shrinks from both the bottom and the top, and annoyingly "runs into" the top border of the tab. Is this supposed to happen? I find it annoying and distracting, especially how it meets the border on the top.
UPDATE: This happens to any tab with the number box in it including reputation/response/etc. tabs on my profile page.
I'm using Google Chrome 25 on Linux.
