Bugzilla CC: lists which scroll show jittery scrolling in recent builds on macOS, when scrolling with the trackpad.

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

Martin, I think this was fixed?
Comment 5 Martin Robinson 2021-06-03 00:27:56 PDT 
Yep, this was fixed in bug 224080 and the original change was landed without having the same issue.

I should say the original change was re-landed.
