Space in the beginning of classname crashes Nextjs app

[callmearta]

Describe the bug

cn(" text-white") causes nextjs page crash in browser giving out of memory error. cn("text-white") fixes the issue. that space took me 6 hours to find out about. Worked fine before new release. cn is also a function that uses clsx and tailwind-merge to combine classnames.

To Reproduce

1. create a nextjs app
2. create the cn function as below:

import { type ClassValue, clsx } from "clsx"
import { twMerge } from "tailwind-merge"
 
export function cn(...inputs: ClassValue[]) {
  return twMerge(clsx(inputs))
}

3. use cn(" text-white") classname as an example.
4. the page crashes in browser while it is on a not much powerful server. I still don't understand why it is related to the server cpu causing client browser to crash.

Expected behavior

No crash in browser.

Environment

nextjs v14.2.5
clsx v2.0.0
