Another thing I realized today is that Chrome and FF accept `;` in input:
```js
const sheet = new CSSStyleSheet
sheet.insertRule('@supports (color: green;) {}')
sheet.cssRules[0].cssText // @supports (color: green;) {}
```
It surprised me because CSS Syntax expects `color: green;` to be parsed with [parse a declaration](https://drafts.csswg.org/css-syntax-3/#parse-a-declaration):
> "Parse a declaration" is used in `@supports` conditions.
It invokes [consume a declaration](https://drafts.csswg.org/css-syntax-3/#consume-a-declaration) but neither consume `;`.
I would say that `;` is part of a declaration and should be consumed in the corresponding algorithm. `<declaration>` could then be defined as any input that can be parsed with *parse a declaration*.
I looked for a corresponding test on WPT but I do not think there is one.
