The most recent problem was that we were setting _lastSetScroll whenever we wrote to scrollTop (and ignoring the next scroll event which matched that offset), but if there was no change to scrollTop, we wouldn't actually get a scroll event, so would ignore some future scroll event instead. Make sure that we only set _lastSetScroll if there's a change to scrollTop. (Fixes element-hq/element-web#1162, more)
