Test case

* SUMMARY
When navigating elements inside a scrolling div (using overflow: auto), WebKit is firing multiple scroll notifications and erroneously resetting the scrollTop value of the containing div with each navigation event.

* STEPS TO REPRODUCE
1. Open the attached test case
2. Turn on VoiceOver and begin navigating the elements inside the scrolling container.

* RESULTS
The container jumps to the newly focused element, but then quickly scrolls back up to it's original position. The focused item should be scrolled to when focused. 

* NOTES
After further investigation, it appears that a second scroll event is also being fired. Check the console in the test case for that evidence.
