Issue passing Authorization header in old Safari?

Hi, I’m using the Authorization header with EventSource polyfill. Everything works great with Chrome, Firefox and recent Safari, but with Safari 9 the header is not sent to the server (it’s missing from the browser request). I see that only since Safari 10.1 the Fetch API is supported. Could this be the reason? And eventually is there anything I can do to fix/workaround the issue?

If it matters, I create the instance this way:

new EventSourcePolyfill(this.url, {
    withCredentials: this.withCredentials,
    lastEventIdQueryParameterName: 'last-id',
    headers: { Authorization: 'Token the_token' },
});

@Yaffle Nope, it’s client side. I still don’t know where exactly the mistake is, but a friend told me that before the last client refactoring (which was big) it stopped working.

It turned out it was an error in my code! Sorry for bothering, thanks for the polyfill.
