[bug]: "Dead" classes in components

[Ivaneyko]

Describe the bug

Hi, after upgrading tailwindcss v3 -> v4 I have bunch of "dead" classes inside the components. It seems to me that the problem may not be in the settings of tailwind itself, but in the components. Since the component is installed already with these classes ( or I miss some point during the migration )

Affected component/components

Button, Input, Dialog ( etc )

How to reproduce

Used this documentation to update: https://ui.shadcn.com/docs/tailwind-v4
Install any component with bunx --bun shadcn@latest add button

System Info

MacOS 15.3.2
Bun 1.2.5
Vite 6.2.2
