* This PR caused the Sidebar.test.ts file tests to fail because TransformStream is not found. * TransformStream exists in the Node version I'm testing with (20), but it still isn't found by Jest * Turns out it is a problem with Jest, and the workaround is the simple package jest-fixed-jsdom, which subclasses JSDOMEnvironment testing environment, placing this and several other dependencies in its global object. * In package.json - add jest-fixed-jsdom as a devDependency * In jest.config.cjs - change testEnvironment to jest-fixed-jsdom
