Issue or Feature

Not sure whether you'll treat this as a jsdom issue (in case jsdom has to change its API or something), but with the RC release, jsdom no longer works.

Steps to Reproduce

With jsdom version 24.1.0

import jsdom from 'jsdom';

const {window: {document}} = new jsdom.JSDOM('');

const canvas = document.createElement('canvas');
const ctx = canvas.getContext('2d');

...gives:

/Users/brett/typeson-registry/node_modules/.pnpm/[email protected][email protected]/node_modules/jsdom/lib/jsdom/living/nodes/HTMLCanvasElement-impl.js:116
  ctx[name] = function (image, ...rest) {
            ^

TypeError: Cannot assign to read only property 'createPattern' of object '#<CanvasRenderingContext2D>'
