Cannot serve `.webp` image in `mdx`

[namdien177]

I'm using hybrid mode with mdx to render the blog content.

With @astrojs/node, the production build serves the image with .webp normally. But with astro-bun, it is always 404 not found for images in webp format.

I checked with the png version of the same image, it serves normally. I also ensured the webp version of the image was not broken.

[//]: # Sample mdx file in the content folder
import { Image } from 'astro:assets';

import ImageCAT6Cable from './cat6-cable.png';

some markdown content here

<figure>
  <Image
    loading={'lazy'}
    src={ImageCAT6Cable}
    alt="cat6 cable" />
  <figcaption>some caption</figcaption>
</figure>

some markdown content here

The image resolved to the correct path (/_astro/cat6-cable<random>.webp) but returns 404. If I change the image path directly to the PNG version (/_astro/cat6-cable<random>.png), it will work just fine.

In the dev environment, it works fine.

But once I build the project and run the entry server with bun /dist/server/entry.mjs, the webp images won't be able to be served as described in the ticket.

Same result here with plain .astro files and an imported png that is converted to webp. Attempts to load it here:

404 http://localhost:4321/_astro/coffee-art.DJfGxfQ-_Z8gfae.webp

dev works fine here too
