Currently, the CSS image-set() function (sister spec to <img srcset>) is specified to do fallback to the less-desirable options if the first choice doesn't load or can't be decoded. I specified it this way because it seemed reasonable, and it's how the similar image() function works (which is specifically designed to be used for fallback). It was later pointed out to me, though, that @srcset doesn't do any fallback. Once it chooses a candidate image, it sticks with it, and if that image is invalid, you just get a broken image. I'd like to harmonize the two, and the CSSWG seems to prefer the fallback behavior. Is there any interest in making @srcset do similar fallback? If not, I'll change image-set() to also not do fallback. ~TJ
