Since r19005 (fix for bug 8360) the Safari RSS sidebar jumps around when you scroll the main content. It uses a scroll event handler to maintain fixed position, and since the scroll events are delayed until after layout and painting, the initial scrolling is visible before the event handler repositions the "pinned" element.

I suppose many sites that use a similar technique are affected.

Fixed by reverting the changes made in bug 8360.
