Go to http://build.webkit.org/waterfall 2. Pick a bot in "layout-tests running" state 3. Follow the stdio link 4. Try to scroll to the bottom. * RESULTS There is no scrollbar. There is no way of knowing how long the document is and reaching bottom of a tall document can be difficult with gestures. The above is a reliable repro but this apparently affects any slow loading (slow network connection included) tall site.
