Deprecated findDOMNode warning in StrictMode

[alextaymx]

This issue was already created(#4577 ) and another related issue is (#4793 ).

I'm still having this warning:

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
