:scope no longer works

[yukulele]

Describe the bug
since happy-dom@13, Element methods with selector string argument seem to no more support :scope selector

• .queySelector()
• .querySelectorAll()
• .matches()

To Reproduce
Steps to reproduce the behavior:

1. npm i happy-dom
2. create this file:

//index.js
import { Window } from 'happy-dom';
const window = new Window();
console.log(window.document.body.matches(':scope')); // false :(

3. node index.js

Expected behavior
element.matches(':scope') should be true

Device:

• OS: linux
• "Browser" happy-dem
• Version @15.11.6
