The Scrollbar of Sisyphus breaks the back button (click "Back", browser remembers where you had scrolled to, can't go that far down, lands at the bottom, triggers second "page" of results) jumping to the bottom of the page, occasionally searching, and forces you to jump to the end of the page repeatedly to figure out where you were. It breaks nearly every UI expectation one has about scrolling (especially on a phone) and several that your browser has about caching.
