@tailwindcss/vite revisions after 4.0.7 are not working with svelte files under viteconfig.resolve.alias

@tailwindcss/vite revisions after 4.0.7 are not working with svelte files under viteconfig.resolve.alias.

It seems css classes are not generated for svelte files under dir defined in viteconfig.resolve.alias。

But @tailwindcss/vite@4.0.7 works

@qjmiao Hey! Can you please post a reproduction for this setup? You may need to add @source directives to scan files outside of your working directory: https://tailwindcss.com/docs/detecting-classes-in-source-files#explicitly-registering-sources

My <vite.config.js> file has the following settings:

resolve: {
alias: {
'@ui': path.resolve(__dirname, '../svx-ui/src'),
}
}

And it seems not all classes in "@ui/.svelte" file are generated with @tailwindcss/vite revisions after 4.0.7

I am seeing a similar issue when using @tailwindcss/vite in a Bazel+rules_js setup...

@tailwindcss/vite@4.0.7 works fine, but any subsequent version does not detect css classes in my sources
