This patch fixes some invalid selectors. CSS nesting doesn't actually
work like this:
```css
.Parent {
&-child {
color: red;
}
}
```
Instead, the `&` is a selector that matches real elements, so here
`color: red` only applies to `.Parent`s that also match `-child`,
which doesn't make a whole lot of sense. It used to work because
the postcss nesting plugin happens to compile it to `.Parent-child`.
