In the FAQ page, when I click on the "How do I search?" header, and the section is expanded, I am moved to the top of the page.
That is not what happens with the other headers in the same page, such as "May I promote products or websites I am affiliated with here?" for which its status (collapsed, not collapsed) is changed all times I click on the header, moving me to the top of the page.
I am using Safari version 5.1 (7534.48.3), and the SE revision is 2011.8.24.3.
