I found that the implementation of -webkit-image-set() in Firefox is completely a standard image-set() mapping, and some new syntaxes are not supported in WebKit/Blink. This seems to be confusing. Does Firefox need to fully follow the existing syntax in WebKit/Blink?

e.g.

```css
.foo {
  background: -webkit-image-set('../img/image-1x.jpg' 1x, '../img/image-2x.jpg' 2x) /* WebKit/Blink invalid */
  background: -webkit-image-set('../img/image-1x.jpg' 1x, linear-gradient(black, white) 2x) /* WebKit/Blink invalid */
  background-image: -webkit-image-set('../img/image-1x.jpg' 1dppx, '../img/image-2x.jpg' 2dppx); /* WebKit/Blink invalid */
}
```
