Bug 13024 – REGRESSION: scrolling a listbox sometimes scrolls the listbox, mostly scrolls the page

• Status: RESOLVED
• Resolution: DUPLICATE
• Component: Forms

* SUMMARY
I'm noticing that scrolling a listbox when trying to book a flight at southwest.com was not scrolling the listbox as smoothly as it should. With 2-finger scrolling, it was mostly incorrect in that it scrolled the page instead of the listbox, and only sometimes scrolled the listbox.  With a mighty mouse, doing a fast scroll was easier and mostly if you do a fast scroll then the listbox gets scrolled, but do it slowly and the page gets scrolled.

* STEPS TO REPRODUCE
0. try this with a laptop - it will reproduce easily
1. open testcase.  
2. use 2-finger scrolling to scroll any of the listboxes on that page

->result: the page is scrolled instead
3. use a mighty mouse, and slowly scroll the listboxes
->result: the page is scrolled instead
4. use a mighty mouse, and quickly scroll the listboxes
->result: the listbox is scrolled as expected

* REGRESSION
yes this is a regression from shipping safari behavior
