Does it support The & nesting selector?

Doesn't Parse The & nesting selector?!


```css
.parentClass {
    color: aqua;
    & .childClass {
      color:aquamarine;
    }
  }
 ```
```js

const parse = createParser();
const selector = parse('& .childClass');
```

```
Error [ParserError]: css-selector-parser parse error: Expected rule but "&" found. Pos: 0.
```
