Re: [csswg-drafts] [css-background-4] add background-layers property to set everything but background-color (#8726)

@ljharb Consider this:

```js
element.style.cssText = "background: var(--b)";
[...element.style].includes("background-color"); // ???
```

At specified-value time we don't know whether the variable will have the value that skips `background-color` from the expansion. So it's an obstacle.
