CDVWebViewDelegate fails to update the webview state properly in iOS when a page loads an iframe using javascript and does a redirect to another page using javascript. Method didFailLoadWithError gets called while in STATE_WAITING_FOR_LOAD_START with a NSURLErrorCancelled (-999) error. Instead of entering STATE_CANCELLED in this situation it always enters STATE_IDLE, which causes didFailLoadWithError event to never fire (which depending on the app, and definitely in our case, can cause a hang condition).
