To reproduce: Place mouse over the red square (which uses position: fixed) in these pages: 1. http://persistent.info/webkit/test-cases/position-fixed-scrolling/document.html 2. http://persistent.info/webkit/test-cases/position-fixed-scrolling/overflow-auto.html 3. http://persistent.info/webkit/test-cases/position-fixed-scrolling/overflow-auto-document.html and use the wheel to scroll. Expected result: 1. Document scrolls 2. overflow: auto div scrolls 3. overflow: auto div scrolls Actual result: 1. Document scrolls 2. Nothing scrolls 3. Document scrolls It might be easiest to skip over position: fixed elements when determining where to fire/propagate wheel events. Firefox 4.0b9 currently behaves like the actual result (WebKit), IE 8 behaves like the expected result.
