WKWebView should implement -encodeWithCoder: and -initWithCoder: to save and restore state, including the owned WKWebViewConfiguration. The existing -initWithCoder: returns nil, and doesn't call super. Among other uses, NSCoding support is required for use in Interface Builder. See radar://17380562 (WKWebView) and radar://18473221 (WKWebViewConfiguration).
Retitling - this now covers WKWebView.
