Limelight opening in SP: Jumping back to top of page

Have a look here: https://ci-clientservices.com/clientdev/llschedule/

You will need to scroll down to see the Limelight thingie.

Click one of the “See Schedule” links. The LL does open, but it jumps back to the top of the page.

I’m pretty sure this is not expected.

Anyone any ideas what is the problem?
