You can write colors in rgb(223 223 223) (without the , now) and this is correct (the coma is the legacy one) but during optimization it swaps rgb to hex, but only the first number and ignoring the rest. So the rgb(223 223 223) becomes #df which is incorrect. Not sure how it treats the / alpha values. But rgb definition changed, and during css optimization it breaks.
