Collection bar obscures Styles section at lower resolution

What steps will reproduce the problem?
1. Go to http://www.google.com/webfonts.
2. Resize the window so that the left-hand frame has a scrollbar.
3. Try to find the "show all styles" option in the left-hand frame.

What is the expected output? What do you see instead?
Expected output: The Styles section is still visible.
Actual output: The Styles section is obscured by the collection bar at the 
bottom of the window, even when the left frame has been scrolled down all the 
way.

What version of the product are you using? On what operating system?
Web site as of 2012/05/20, Firefox 12.0, Mac OS X.

Please provide any additional information below.
This seems as if it could be solved by having an empty div at the end of the 
left frame's content that's exactly the same height as the collection bar.
