<pre>And remove the workaround from RenderLayerBacking::updateAfterLayout()
if (!compositor().compositingLayersNeedRebuild()) {
// Calling updateGeometry() here gives incorrect results, because the
// position of this layer's GraphicsLayer depends on the position of our compositing
// ancestor's GraphicsLayer. That cannot be determined until all the descendant
// RenderLayers of that ancestor have been processed via updateLayerPositions().
//
// The solution is to update compositing children of this layer here,
// via updateCompositingChildrenGeometry().
(We need to position the parent graphics layer in order to be able to compute the correct descendant graphics layers positions.)</pre>
