What are the limitations of React Error Boundaries when using the npm package?

React Error Boundaries, including those implemented with npm packages, have some limitations: - They do not catch errors in event handlers. - They do not catch errors in asynchronous code (e.g., `setTimeout` or `requestAnimationFrame` callbacks). - They do not catch errors thrown in their own component. - They do not catch errors in rendering of the Error Boundary itself. - They do not catch errors in the lifecycle methods of their own component or in the component itself. For these, you would typically use `componentDidCatch` or `getDerivedStateFromError` directly if building a custom boundary, or rely on the underlying error handling of the library.
