Created attachment 351460 [details] Testcase When will-change changes, rareNonInheritedDataChangeRequiresLayout() sets a flag in changedContextSensitiveProperties, and then RenderStyle::changeRequiresLayerRepaint sees a z-index changes and says that repaint is required. Then RenderElement::adjustStyleDifference() takes the max of StyleDifference::RecompositeLayer and StyleDifference::Repaint and issues a repaint. However, we need will-change to dirty z-order lists and and trigger compositing updates
