issue(InAppBrowser) Invalid event target

Ionic Native

The following works fine for me in Android:

loginFacebook(): Promise<any> {
  return new Promise((resolve, reject) => {
    if (this.platform.is('cordova')) {
      var browserRef = this.inAppBrowser
        .create(`https://www.facebook.com/v2.9/dialog/oauth?client_id=${CLIENT_ID}&redirect_uri=${BASE_URL}/callback&response_type=token&scope=email`, "_blank", "location=no,clearsessioncache=yes,clearcache=yes");

      const exitSubscription: Subscription = browserRef.on("exit").subscribe((event) => {
        console.error("The Facebook sign in flow was canceled");
        reject(new Error("The Facebook sign in flow was canceled"));
      });

      browserRef.on("loadstart").subscribe((event) => {
        console.log(event);
        if ((event.url).indexOf(`${BASE_URL}/callback`) === 0) {
          console.log(event.url);
          exitSubscription.unsubscribe();
          browserRef.close();
          var responseParameters = ((event.url).split("#")[1]).split("&");
          var parsedResponse = {};
          for (var i = 0; i < responseParameters.length; i++) {
            parsedResponse[responseParameters[i].split("=")[0]] = responseParameters[i].split("=")[1];
          }
          if (parsedResponse["access_token"] !== undefined && parsedResponse["access_token"] !== null) {
            console.log(parsedResponse);
            resolve(parsedResponse);
          } else {
            console.error("Problem authenticating with Facebook");
            reject(new Error("Problem authenticating with Facebook"));
          }
        }
      });
    } else {
      console.error("loadstart events are not being fired in browser.");
      reject(new Error("loadstart events are not being fired in browser."));
    }
  });
}

Obviously it doesn’t work in Browser because of this: https://github.com/apache/cordova-plugin-inappbrowser#browser-quirks-1
