https://bugs.webkit.org/show_bug.cgi?id=124042 Patch by Mihai Maerean <mmaerean@adobe.com> on 2014-01-23 Reviewed by Mihnea Ovidenie. Source/WebCore: If there's a clipping GraphicsLayer on the hierarchy, substract its offset, since it's its parent that positions us. Tests: compositing/regions/position-layer-inside-region-overflow-hidden.html compositing/regions/position-layer-inside-overflow-hidden.html compositing/regions/position-layers-inside-region-overflow-hidden.html compositing/regions/position-layers-inside-regions-overflow-hidden.html * rendering/RenderLayerBacking.cpp: (WebCore::RenderLayerBacking::adjustAncestorCompositingBoundsForFlowThread): The position must also be correct when the region has box-shadow that inflates the region's layer. The composited layers from the flow thread should be rendered in the same position whether the associated region has clipping or not. Using the position of the clipping layer instead of the location of the clipbox makes it also work with box-shadow that inflates the region's graphics layer.
