Reproduction

https://stackblitz.com/edit/github-sh3gjl
To see the redirect, you need to open the preview in its own browser window.

Local instructions:

npx nuxi@latest init public-error
cd public-error
npm run dev

Visit http://localhost:3000
Open DevTools and enable routing

mkdir pages/test
cp pages/index.vue pages/test/index.vue
mkdir public/test

Visit http://localhost:3000/test
301 redirect to /test/

Describe the bug

When using the dev server, when a route shares the exact same string as a folder within the public directory, a combination of vite dev server, h3, and send libraries check the public subfolder paths and on discovering a matching string and that it is a folder, then does a 301 redirect with a trailing slash. It never hits nitro until after the redirect occurs.
