The Tailwind utilities layer is absent in the reproduction.
Observe how the class space-y-4 is not applied between the email input and the login button.

Please see details in full issue as originally posted here : Baroshem/nuxt-security#576

This is Nuxt Security team.
Our context is the Nuxt Framework, but the issue appears to be unrelated to Nuxt.
Our investigation found that the bug only appears when Vite is used with option { build: { minify: true } } as documented in Vite here : https://vite.dev/config/build-options#build-minify

As a temporary workaround, we are disabling Vite's build minification.
However we would like to be able to minify builds again. This breaks Tailwind for now.
