Subject: [PATCH] Fix failing unit tests * 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
