I use onNavigationStateChange to monitor the change of URL: `onNavigationStateChange = (navState) => { console.log(navState) }` however, it will not be called if the page your WKWebView is trying to open is a SPA. # Environment ``` OS: macOS Sierra 10.13.6 Node: 8.9.1 Yarn: 0.24.5 npm: 5.4.0 Packages: (wanted => installed) react-native: 0.53.0 react: 16.3.1 react-native-wkwebview-reborn: 1.22.0 ``` ## Steps to Reproduce 1.WKWebView opens https://eos.live and logs in 2.Click to jump to other pages When the web page in WKWebView uses history.pushState () to change URL, onNavigationStateChange does not execute ## Expected Behavior onNavigationStateChange executes after each URL change ## Actual Behavior onNavigationStateChange does not execute every time URL changes ## Reproducible Demo ``` <WKWebView onNavigationStateChange={this.onNavigationStateChange.bind(this)} source={{uri:"https://eos.live"}} allowsInlineMediaPlayback={true} domStorageEnabled={true} javaScriptEnabled={true} scalesPageToFit={false} /> ```
