react-error-overlay uses deprecated method findDOMNode() which shows an error in React.StrictMode

[jboler]

Describe the bug

findDOMNode() is deprecated and should not be used - see Official React Docs.

When using <React.StrictMode> the below error appears in the browser console:

Further investigation of the stack trace finds usage of findDOMNode in node_modules/react-error-overlay/lib/index.js

Similarly react-error-overlay is using UNSAFE_componentWillMount() which is causing a StrictMode error.
