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

Although, there is some special handling of invalid images, particularly fror properties that can take `<image>` or `none`:

> An invalid image is rendered as a solid-color [transparent](https://drafts.csswg.org/css-color-4/#valdef-color-transparent) image with no [natural dimensions](https://drafts.csswg.org/css-images-3/#natural-dimensions). However, [invalid images](https://drafts.csswg.org/css-images-4/#invalid-image) can trigger error-handling clauses in some contexts. For example, an invalid image in [list-style-image](https://drafts.csswg.org/css-lists-3/#propdef-list-style-image) it is treated as [none](https://drafts.csswg.org/css-lists-3/#valdef-list-style-type-none), allowing the [list-style-type](https://drafts.csswg.org/css-lists-3/#propdef-list-style-type) to render in its place.
