Basic info:

• Node.js version: 16.20.0
• jsdom version: 22.1.0

Minimal reproduction case

const { JSDOM } = require("jsdom");

const dom = new JSDOM('<div>hello</div>');

const element = dom.window.document.querySelector('div');

console.log('active', element.matches(':active'));

It logs active true, but should log active false. This behaves correctly in the browser.

edit: I first thought it was due to the update from 21 to 22, but it might not be related. Investigating further
edit2: After some digging, I found nwsapi 2.2.7 to be the culprit. The fix (a revert) seems to be already in the master branch, but it has not been released yet. I can locally override to 2.2.6 to make this work again. You might want to as well until the next version is released.

How does similar code behave in browsers?
