addEventListener does not work on iOS

events are not being fired for loadstop and loadstart (have not tested the rest of the events) on iOS (works fine on Android)

Using the following code:

const browser = cordova.InAppBrowser.open(`https://${this.companyName}.${this.domain}/api/v1/saml`, "_blank", "location=no,toolbar=no");
browser.addEventListener("loadstop", (event: InAppBrowserEvent) => {
  console.log("page changed", event.url);
});

Tested on Cordova 7.1.0 and cordova-plugin-inappbrowser 3.0.0

The plugin repo does mention an issue with OSX (_blank not being supported, and events relying on _blank) but this should not effect iOS to the best of my knowledge
