Fix 'spoof-css' — DOMRect is set incorrectly

[AdamWr]

Steps to reproduce:

1. Add this rule:

example.org#%#//scriptlet('spoof-css', 'body', 'visibility', 'hidden')

2. Go to - https://example.org/
3. In browser console run:

const { height, width } = document.body.getBoundingClientRect();
console.log('height:', height);
console.log('width:', width);

width returns incorrect value.
It's probably due to this line:

Scriptlets/src/scriptlets/spoof-css.js

Line 212 in 3ba245f

const newDOMRect = new window.DOMRect(rect.x, rect.y, top, bottom, width, height, left, right);

and perhaps should be changed to:

 const newDOMRect = new window.DOMRect(rect.x, rect.y, width, height);
