+        [Qt] REGRESSION(r57638): tst_qwebframe::objectDeleted() fails
+        https://bugs.webkit.org/show_bug.cgi?id=38316
+
+        Accessing properties of a deleted objects doesn't throw an exception
+        anymore.
+
+        Continue to expose the QObject class wrapper for objects that
+        previously existed but don't exist anymore. QtClass is safe to
+        use with a deleted QObject.

+        (JSC::Bindings::QtInstance::getClass): Return null only if m_class
+        doesn't exist yet and there's no m_object.

+        [Qt] GraphicsLayer: preserves-3d and backface visibility
+        https://bugs.webkit.org/show_bug.cgi?id=35312
+
+        Implement preserves-3d by maintaining the 3D transformation heirarchy inside GraphicsLayerQt, and extrapolating
+        the relative QTransform. When the extrapolation fails (un-invertible matrix) we ignore the transformation change.
