<pre>To reproduce:
1. Open <a href="http://output.jsbin.com/nayoxe/quiet">http://output.jsbin.com/nayoxe/quiet</a> on iOS
2. Try to scroll fast
Observe:
Top and bottom elements styled with `position:fixed` jump and flicker.
Expected:
`position:fixed` elements should stay put.
Description:
This is a somewhat specific example. It's uses `overflow:auto` scrolling inside of an iframed document, which is a workaround for the fact that iOS doesn't allow iframes to scroll.
