💅 False negative `noUnusedVariables` in Astro file

[1v3n]

Environment information

Hey,

inside an Astro file I get an false noUnusedVariables error.

My biome setup for that:

"rules": {
  "recommended": true,
  "correctness": {
    "noUnusedVariables": "error"
  }
}

index.astro

---
const { title } = Astro.props;
---

<span>{title}</span>

Causes

 ✖ This variable is unused.

  > 2 │ const { title } = Astro.props;
      │         ^^^^^
    3 │ 

  ℹ Unused variables usually are result of incomplete refactoring, typos and other source of bugs.

Rule name

noUnusedVariables

Expected result

I would not expect an error, as the variable is used In the JSX part of the Astro file.

Biome doesn't fully support Astro files, therefore I needed to set this:

 "globals": ["Astro"]
