Steps to reproduce the problem:
1. go to Settings
2. click "Customize fonts" or "Manage search engines"

What is the expected behavior?
The subpage fits available height exactly.

What went wrong?
The subpage is too tall/long thus causing an unnecessary vertical scrollbar to appear, which in turn jerks the content column on the page a few pixels to the left to center it in the reduced window width.

Did this work before? Yes See bisect below
