To reproduce, expand the CC list in a bug with lots of CCs, and test fingers-down scrolling in the list.

Yep, this was fixed in bug 224080 and the original change was landed without having the same issue. *** This bug has been marked as a duplicate of bug 224080 ***

I should say the original change was re-landed.
