Web Compatibility Support • 34.2: workaround for CloudFlare image resizing breaks loading of images on rohlik.cz

Hello, after updating to version 34.2, the rohlik.cz online grocery-store fails to load many images. Disabling the "network.url.cloudflare_image_resizing.enabled" pref restores the correct behavior (product images are cropped by default, I am using a custom style to workaround that). One such image has url:

CODE:

https://www.rohlik.cz/cdn-cgi/image/f=auto,w=256,h=256/https://cdn.rohlik.cz/images/navigation/richicons/fruits-and-veggies.png?v3

I am not sure what problem this workaround was supposed to solve as I have not experienced the described issue, but I am keeping it off for now.
