   The Android implementation is an exact emulation of the native implementation of `postMessage()` in WKWebView on iOS
    i.e. `webkit.messageHandlers.cordova_iab.postMessage()` calls the native WKWebView implementation of that function.
   If you pass anything other than a stringified JSON object to `postMessage()` in WKWebView, it will fail silently (no errors in native or JS consoles).
   
   To make Android behaviour differently, e.g. make any string valid as a `postMessage()` argument, would cause cross-platform confusion as it would work on Android but fail silently in WKWebView on iOS.
