Preconnect

Hi Frank,
First of all, many thanks for your plugin! It is a lot of work and knowledge you share with the community.

Going straight to my question:
I have installed AO with CriticalCSS plugin and when auditing my website with Google Audits I received this alert.

Consider adding preconnect or dns-prefetch resource hints to establish early connections to important third-party origins.

https://www.googletagmanager.com 330 ms
https://fonts.googleapis.com 340 ms

So I added them to the Preconnect to 3rd party domains field like this:
https://fonts.googleapis.com,https://www.googletagmanager.com

But now I see this alert

* A preconnect <link> was found for https://fonts.googleapis.com but was not used by the browser. Check that you are using the crossorigin attribute properly.
* A preconnect <link> was found for https://www.googletagmanager.com but was not used by the browser. Check that you are using the crossorigin attribute properly.

Is there a way to force the crossorigin attribute?

Thanks
