+                                            parent document, relying on the fact that the frame's platform view can host
+                                            a layer-backed view. However, this ran into bugs (rdar://problem/18862298),
+                                            and triggers the assertion at the end of FrameView::updateLayoutAndStyleIfNeededRecursive(),
