StrictMode check about

[linonetwo]

I got this when using react-collapse-pane in React.StrictMode

Warning: findDOMNode is deprecated in StrictMode. findDOMNode was passed an instance of Transition which is inside StrictMode. Instead, add a ref directly to the element you want to reference. Learn more about using refs safely here: https://reactjs.org/link/strict-mode-find-node

allotment is a good alternative that works with React 17.
