Given
```js
function ThrowInEffect() {
  React.useEffect(() => {
    throw new Error('passive effect')
  }, [])
  return null;
}
```

In React 17 this error got logged to the console (and triggered the error overlay in create-react-app) regardless of whether `ThrowInEffect` was a child of an Error Boundary or not.

In React 18 (`createRoot` and legacy root API) an Error Boundary will prevent logging that error to the console (and not trigger the error overlay in create-react-app).

Errors during render work like they did in React 17.
