Describe the Bug

I create a page e-index.astro, and the astro config is build.format:"preserve"

In dev mode or preview mode, the 'e-index.html' page cannot found. But it can build successfully.

sample code :

What's the expected result?

in dev mode, to load the page e-index.html in browser

Yes, I have a GitHub repo, that can reproduce the problem. Here it is https://github.com/jasper2virtual/astroissue
This is a Astrojs project, you can reproduce the problem :

1. npm run dev
2. use browser to visit http://localhost:4321/e-index.html
3. Then the browser show 404 error

4. And it is weird that it show the page at http://localhost:4321/e-index/index.html

5. But the e-index.html can be built successfully, after 'npm run build'
