FindDomNode warning with react strict mode

[jRichardeau]

This is not really a bug but when using react in strict mode a warning appears linked to OutsideClickHandler :

Warning: findDOMNode is deprecated in StrictMode. findDOMNode was passed an instance of r which is inside StrictMode. Instead, add a ref directly to the element you want to reference.

To Reproduce
Run react in strict mode and use calendarContainer prop

Expected behavior
I think this can be solved with this Pomax/react-onclickoutside#319

Thank you
