Google Book Search book preview loads page images dynamically as you scroll through the book. In TOT, when a new image starts loading, the progress indicator in the address bar goes on, then when the page is loaded, the whole page sort of flashes and the main view snaps to the top of the page. To reproduce, open the URL and start scrolling down slowly. This does not happen in Safari 3.0.4.

Sounds like we need to roll r30571 out then.
This no longer reproduces.
