Webpagetest using hardcoded protocol in results?

I’m running our website on Windows Server 2013 under IIS 8.5 which does not support http/2 yet in the waterfall results the google analytics javascript and jquery library from code.jquery.com are both displayed as using http/2 in the popup window when clicked on. Is that because the waterfall results are hardcoded for those particular applications? Or am I just not understanding what I’m seeing?

Edit: see attached image.

In the screenshot it means that the browser established at HTTP/2 connection with www.google-analytics.com

The server you’re using won’t make any difference to the connection that’s established with other hosts

Thanks for the clarification!
