Describe the Bug

Steps to reproduce:

1. Create a new project with minimal template (Path: D:\dev\astro-demo)

2. Edit src/pages/index.astro, insert some style at bottom:

   <style>h1 { color: orange; }</style>
   

3. Open a terminal and change path to d:\dev\astro-demo (note here)

4. Run npm run dev and see in browser

What's the expected result?

h1 should be orange, but not. Then change path to case correct path, it becomes normal.
