`"length" is read-only` error when imported

I see this happening in Vite and [CodeSandbox](https://codesandbox.io/s/priceless-zhukovsky-zms6z?file=/src/index.js), which I believe is based on Parcel. It seems to be OK in Webpack, though. I suspect the difference is whether the package is imported with ES Modules or in Strict Mode (which the former implies).
