Infinite scroll does not work with React Strict Mode

[delasource]

Subject of the issue

Within the tag <React.StrictMode> a DateRangePicker component does not work. It can not track the scrollposition to show the full calender. Only "months-prop +1" months are visible.

[BUG] Bug Reproduce Steps

Create a vite project and add the infinite-scroll-example code under the StrictMode-Element.

[BUG] Expected behaviour

Look like on demo page.
