Comment 2

[Hiroyuki Ikezoe (:hiro)]

I could reproduce the failure locally.

"Waiting for a wheel event and a pair of flushing APZ repaints and waiting for MozAfterPaint" is not sufficient for some reasons to reflect the scroll position on the main-thread caused by wheel scrolling on APZ side. I've confirmed waiting for a scroll event fixed the failure locally.
