Why the import from npm is not working but working when copy-pasted and imported from file?

Hi, I wanted to use that package: https://www.npmjs.com/package/react-card-flip

When I have imported component as documented

import FlipCard from 'react-card-flip';

I got

So, I jumped to source of react-card-flip to check is any code that is not compatible with SSR: https://github.com/AaronCCWong/react-card-flip/blob/master/src/ReactCardFlip.tsx

I have not found any issue, so copy-pasted code into my source in routes near my route, and now when import that code like

import FlipCard from './flip-card';

it is working

I am a little bit confused by that, I thought error above signaling about error during SSR due to incompatible with node runtime calls, but then copied code also should not work, could probably someone help to understand why it is working in that way?
