Global error listeners not called for thrown errors

[with-heart]

Describe the bug

When registering a global error listener using addEventListener with both jsdom and happy-dom environments, the listener is not called by an error being thrown.

Dispatching an ErrorEvent using dispatchEvent does cause the listener to be called.

The error you threw is correctly caught because there is a try/catch handler for every test, so it's not unhandled. I don't think you can trigger a global error event in tests because even file imports have guards, you'd need to detach the throw from the current context somehow, and the only way I know how it is by throwing an error asynchronously and not awaiting the promise, but that would be unhandledrejection, not error.
