Reproducible: Always

here is an example of using scrollbars in ui widgets: http://oil21.org/~j/tmp/oxjs/_dev/demos/ui/

This is bug 77790 isn't it?

Post about how Mozilla Bespin needs custom scrollbars: http://almaer.com/blog/creating-custom-scrollbars-with-css-how-css-isnt-great-for-every-task "That being said, at least we do have the ability to do this kind of thing now. I hope that other browsers follow WebKit in this instance."

But why not? :( Chrome: https://i.imgur.com/41An3n2.png Firefox: https://i.imgur.com/L1upYt6.png See the difference?

Please see the bug this duplicates to (bug 77790). There is news of a spec there. In general, bugs are not the place to argue for or against changes to be made.
