Re: [csswg-drafts] [css-images-3][css-color-5] color-mix() and cross-fade() have different serialization order? (#9405) from Chris Lilley via GitHub on 2023-09-25 (public-css-archive@w3.org from September 2023)

I could make a PR to change cross-fade to conform to the (now widely implemented) `color-mix` serialization order, but:

- is it worth doing?
- are these strictly comparable?

If it is just flipping the order to 

```css
<cf-image> =  [ <image> | <color> ] && <percentage [0,100]>?
```

then maybe that is helpful, but what about the missing `<color-interpolation-method>`? It looks like CSS Images 4 [cross-fade](https://drafts.csswg.org/css-images-4/#cross-fade-function) doesn't discuss what colorspace is used for calculation _at all_. And there are seemingly [no tests](https://wpt.fyi/results/css/css-images?label=experimental&label=master&aligned)?
