I thought about adding this as a comment to Feedback wanted: link GitHub projects to SO Careers profile but since this is a UI bug, I thought it was a big enough deal for its own question.
When a user has more than 3 github profiles listed on their careers page the link for "display more" renders the full anchor tag on the client.
Please see My CV on Careers
A potential employer is going to look at my page today... so it's a little embarrassing. Especially since I was going to evangelize careers to their HR department.
