Summary Quirksmode: Fixed / Overflow > Positioned objects get hidden when scrolling

Reported 2006-06-29 23:05:53 PDT
When you have a object with a relative position, inside an object with overflow hidden, inside a fixed object, the relatively positioned object gets clipped when you scroll the page. The sample page has a simple set of examples: http://eeoh.com.au/bugTesting/safari_fixed_overflow_relative_scroll_bug.html

I have found an addition to this bug, as well as the original case the same things happens with an overflow hidden object, inside an overflow hidden object, inside a fixed object. I'll attach a more complete example.

The bug is broader than I had thought. In addition to the original bug... If you have a positioned object, or an overflow hidden object inside a fixed object with overflow hidden then all the positioned objects get clipped on scroll.
