Observable.ajax does not appear to recognize "withCredentials" mode for CORS

[wizardwerdna]

(<any> Observable).ajax({
  url: `${YQL_BASE}?q=${YQL_QUERY}&${YQL_FORMAT}`,
  crossDomain: true,
  withCredentials: false
})
.subscribe(
  x => console.log("ajax", x),
  err => console.log("ajax err", err)
);

Observable.ajax does not appear to recognize the withCredentials mode for CORS, either expressly or as the promised default.

This code, when run on Chrome, yields substantially the following:

XMLHttpRequest cannot load . A wildcard '*' cannot be used in the 'Access-Control-Allow-Origin' header when the credentials flag is true. Origin 'http://localhost:8080' is therefore not allowed access. The credentials mode of an XMLHttpRequest is controlled by the withCredentials attribute.

and the browser console message:

ajax err AjaxError {message: "ajax error 0", xhr: XMLHttpRequest, request: Object, status: 0}

The works when clicked in the browser error message. Similar code, using jQuery or fetch and Observable.fromPromise, works fine.

Related with #1732, not exact dupe but expect to be resolved at once.

I expect #1758 covers this by supporting withCredentials in options to create XHR, closing issue. Please feel freely reopen if issue persists with latest master.
