For this page, my clients notices that the images are cropped up to the height of 30px, keeping the same width. https://www.agricamp.be/producten/akkerbouw/meststoffen/kalkmeststoffen/
After investigation, it's a problem with the Edge browser. There's a ticket over here: https://developer.microsoft.com/en-us/microsoft-edge/platform/issues/7778808/
It's a bizar problem, on that client pc: when i go to developper tools and remove the srcset in code, the image is back to normal. When i refresh the page, the image stays OK. Even when it has the srcset back again in it's code. The problem is very random, not all images are affected. There is a caching plugin activated: WP Rocket. Maybe a caching thing?
It seems that Microsoft doesn't do anything to fix it. Ticket is a few months old. Is there someone here who has the same issue, and found a solution. The only solution (imo) is to strip the srcset (which is WordPress default functionality), but i rather won't do this.
