Fetch an imported asset URL responds with wrong content in dev mode

[yume-chan]

Describe the bug

1. Create an asset named text with content I'm a text file.
2. Add the asset to assetsInclude in vite.config.js: assetsInclude: ["text"],
3. Import the asset: import BinUrl from './text';
4. Use fetch to retrieve its content: fetch(BinUrl).then(response => response.text()).then(text => document.querySelector('#app').innerHTML = text);

In dev mode, the result is export default "/text"

In preview mode, the result is I'm a text file. (correct)

Missing file extension? .txt for instance.

The asset file is in a dependency package I have no control. Also it works in Webpack and vite build.
