issues migrating from findDOMNode

Timeline

1. <= 16.3: findDOMNode is discouraged but accepted for certain use cases
2. 16.3 (2018-03-28): forwardRef is introduced: It can be used in HOCs to avoid using findDOMNode on the enhanced component
3. 16.6 (2018-10-23): findDOMNode is deprecated in React.StrictMode
4. 16.7.alpha (2018-10-24): React.Concurrent mode is released: This mode extends React.StrictMode in a way that findDOMNode is deprecated in that mode too.
