WebPageTest doesn't recognize Fastly CDN

Im using Cloudinary service(https://cloudinary.com/) to serve images for my website.
Cloudinary uses Fastly CDN under the hood.
When im trying to test my website using WebPageTest, results say that my images don’t use CDN at all.
Seems like WebPageTest doesn’t recognize Fasly CDN, but github(https://github.com/WPO-Foundation/wptagent/blob/master/internal/optimization_checks.py#L48) says it do recognize.

Hi! Do you have a WebPageTest run that shows this behaviour?

Regards, Leon

I didn’t see any issue with CDN, please share the issue screenshot or sample script used.
