Doesn't work with the vite dev server

[DeluxeOwl]

This is a barebones vite project and localias install.

❯ bun create vite
✔ Project name: … repro
✔ Select a framework: › React
✔ Select a variant: › TypeScript

Scaffolding project in /private/tmp/A2D5DA12/repro...

Done. Now run:

  cd repro
  bun install
  bun run dev

❯ bun run dev
$ vite
  VITE v6.1.1  ready in 96 ms

  ➜  Local:   http://localhost:5173/
  ➜  Network: use --host to expose
  ➜  press h + enter to show help

in another terminal, running and trying curl https://frontend.local/ or going from the browser

Any ideas?

Note: I found that it works with bun dev --host and setting allowedHosts in vite, but I have no clue why it doesnt work with localhost

import { defineConfig } from "vite";
import react from "@vitejs/plugin-react";

// https://vite.dev/config/
export default defineConfig({
	plugins: [react()],
	server: {
		allowedHosts: ["frontend.local"],
	},
});

Thanks for writing in — I have a draft PR open to fix this (I think), but I need to do a little more testing and writing before I can merge it.
