Hi, "min" or "max" expressions are completely ignored by sizes in Safari, while they are properly honored in both Chrome and Firefox. We had a few min() based calculation, which caused Safari desktop to only pickup the biggest size. You can find a minimal reproduction case here: https://codepen.io/bakura10/pen/PodgbzN Chrome and Firefox both show the low-resolution image due to the min clause, while Safari ignores it and uses the bigger image. Thanks!

I am able to reproduce using attached test case on STP175 where Safari show '1000*400' while both Chrome Canary 117 and Firefox Nightly 118 show 200*100.
