Unix domain socket not working with node:http

[StreetStrider]

Version: deno 2.1.4+e6869d7

After recent deno websocket improvements, I got a lot of my ws code work. However, unix domain sockets seems to not be created.
deno-sock.tar.gz

import { Server } from 'node:http'
import { WebSocketServer } from 'npm:[email protected]'

const server = new Server().listen({ path: 'ws+unix:///tmp/deno.sock' })
const wss = new WebSocketServer({ server })

wss.on('listening', () => console.log('listening'))
wss.on('error', () => console.log('error'))

This should create socket file in /tmp after listening, but it does not happen.
