leading classes are getting removed if applied in the middle

[ubaid-myalfred]

Describe the bug

Tailwind merge remove the leading classes if it is applied in the middle of the class. It is only working if I apply it on the end.

To Reproduce

Not working
className='text-[1.5rem]! leading-[1.75rem]! md:text-2xl lg:text-[1.625rem] xl:leading-[2.188rem]! xl:text-3xl! max-w-3xl! text-primary-headingDark80!'

Working
className='text-[1.5rem]! leading-[1.75rem]! md:text-2xl lg:text-[1.625rem] xl:text-3xl! max-w-3xl! text-primary-headingDark80! xl:leading-[2.188rem]!'

Expected behavior

Leading class should be applied but it keeps getting removed

Environment

Tailwindcss v4.1.4
tailwind merge v3.2.0

Hey @ubaid-myalfred! 👋

Just tested it out in https://codesandbox.io/p/sandbox/spjzgc and the only class that gets removed is xl:leading-[2.188rem]!. Are you sure that the problem doesn't come from a different part of your codebase?
