Bug 1719862 [wpt PR 29622] - [CompositeAfterPaint] Don't fragment composited scrollers, a=testonly Automatic update from web-platform-tests [CompositeAfterPaint] Don't fragment composited scrollers Fragmenting composited scrollers caused multiple scroll nodes and layers with the same element id which confused cc. To prevent fragmentation of composited scrollers, use the same pre-CAP method for directly composited layers. This CL is not needed for LayoutNGBlockFragmentation.
