The purpose of ResetWinsInCascade() in SetTarget() ensures that RequestRestyle(Layer) is invoked for the new target in the case when composite order or CSS cascading or order is changed due to chaging target element, but RequestRestyle(Layer) will be called right after setting the new target in SetTarget() explicitly.
