Testing Vite proxy configuration with WebSocket support.

bun install
bun run dev   # Vite

In another terminal, run the WebSocket server (listens on 8078):

bun server.js

Then, open your browser and navigate to http://localhost:5173 and open the developer console to see how it doesn't work.

In development console you can directly connect to the WebSocket server using:

const ws = new WebSocket('ws://localhost:8078')
ws.onmessage = console.log
ws.send("Testing")

This should work, and the server also prints the message on console.
