Help squash an iOS-specific bug: expertise needed in html5, javascript, and jquery.js

The web site [login to view URL] is nearing completion but we need some help optimizing for iOS. A number of minor issues need investigating, but there’s one critical problem that only happens on iOS. To reproduce, click the following link: [login to view URL] If you scroll down in the top-right list (see attached screenshot) and click on a time-code it should scroll the item you click on to the top of the window. This works fine on all browsers apart from iOS where occasionally it will scroll that window all the way back to 00:00. More detailed documentation is available.
