Won't optimize any images in "public" with Remix

[natmfat]

Describe the Bug

I'm using Vite with Remix. For some reason, images that are imported in the app directory are optimized, but images in the public directory or not, even when includePublic true.

Steps to reproduce

1. pnpm create vite & select "Remix"
2. pnpm add vite-plugin-image-optimizer sharp svgo -D
3. add ViteImageOptimizer({ includePublic: true }) to vite.config.ts
4. add some images (or not, Remix comes with a few logos)

Alternatively, clone this repo to reproduce: https://github.com/natmfat/bug-vite-plugin-image-optimizer

> pnpm run build
...
✨ [vite-plugin-image-optimizer] - optimized images successfully:
server/assets/portfolio-home-DOw3Ebwk.png  -73%    cached original: 336.98 kB; cached: 92.32 kB

I expected images in the "public" directory to be transformed as well, not just ones that are imported.
