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.

Does this have any relationship to bug 47036?

I'm not sure, I haven't looked at the code that's involved.
