I meant a test for this bug, not for bug #148182, that is attached to this bug already, but that depends on bug #153479. With current trunk, scrollable areas do actually scroll after being restored from the page cache when they receive wheel events, but the scroll animator is not notified. That's not a problem at all for non-overlay scrollbars that are always visible, but for overlay scrollbars that are shown when the mouse enters the scrollable area, we never see them (unless hovered) when the page is restored from the page cache.
