Configuration

import js from '@eslint/js'
import tseslint from 'typescript-eslint'
import eslintPluginAstro from 'eslint-plugin-astro'
import eslintConfigPrettier from 'eslint-config-prettier'

export default [
    js.configs.recommended,
    ...tseslint.configs.recommended,
    ...eslintPluginAstro.configs.recommended,
    eslintConfigPrettier,
    {
        rules: {
            'astro/no-unused-css-selector': 'warn',
        },
    },
]

const { name } = Astro.props
---

<div class="hello">
    <p>Hello, {name}!</p>
</div>

<style lang="scss">
    @use '../styles/_mixins.scss' as mixins;

    .ok {
        color: red;

        @include mixins.breakpoint('small') {
            display: none;
        }
    }
</style>

What did you expect to happen?

A warning should be thrown for the unused .ok selector.

What actually happened?

No error was logged.

Additional comments

Everything works if the styles are modified to this:

<style lang="scss">
    .ok {
        color: red;
    }
</style>

So it seems to be the SCSS-specific code that's causing the issue.
