See bug 1228407 comment 17 for backstory. The patch in that bug was intended to make APZ smooth scrolling better when there's a continual flow of incoming smooth-scroll requests from JS. However the patch leaves an edge case unfixed, where if the page has two separate scrollframes and they are getting smooth-scrolled by JS in an interleaved fashion, then we might run into badness. Filing this bug to take care of this in a follow-up.
