Summary:
There is a problem that the `mediaPlaybackRequiresUserAction` property does not work in WKWebView(`useWebKit`) under iOS 10.
I fully know you are currently working to migrate the core's WebView to the standalone `react-native-webview` project. This has already been submitted to PR in `react-native-webview` and will be merged soon. I hope this fix applies to `react-native` before your migration is done.
