Re: [csswg-drafts] [css-color-5] What is the computed value of light-dark(none, none)? (#13866)

> FWIW Firefox doesn't support none in `light-dark()` for this reason, and the discussion in [#12513](https://github.com/w3c/csswg-drafts/issues/12513) and above seems to indicate it's not so trivial to consider `none` an image everywhere.

Hm. It looks like it's supported in Firefox nightly with this case?

```html
<!DOCTYPE html>
<style>
  div {
    background-image: linear-gradient(green);
    background-image: light-dark(none, none);
    width: 100px;
    height: 100px;
  }
</style>
<div></div>
```
