.closest('#null') or .closest('.null') returns self #3466
Description
Basic info:
- Node.js version: 14.19.3
- jsdom version: 20.0.3
Minimal reproduction case
"null" selectors like #null and .null that shouldn't match anything are matching the original node when queried with .closest().
const { JSDOM } = require('jsdom');
const { window } = new JSDOM(`<p>foo</p>`);
const p = window.document.querySelector('p');
// These return null, as expected
console.log(p.closest('#whatever'));
console.log(p.closest('.whatever'));
// These return the HTMLParagraphElement
console.log(p.closest('#null'));
console.log(p.closest('.null'));How does similar code behave in browsers?
Returns null when there is no match.
