Changing input length does not re-render the component with new input length

This occurs when dynamically passing the input length. Check this sandbox I have created.
https://codesandbox.io/s/react-pin-input-forked-13y1m?file=/src/App.js

Reproduce the behavior using the linked CodeSandbox, starting with src/App.js and the dynamically passed input length. Trace why the React component does not update when that value changes, then verify that changing the length causes the rendered inputs to match the new value.
