Http server node:http does not call connect event returning 400

[tarik02]

What version of Bun is running?

1.1.43+76800b049

What platform is your computer?

Darwin 24.0.0 arm64 arm

What steps can reproduce the bug?

Use following code to create http proxy:

import { createServer } from 'node:http';

const server = createServer();

server.on('connect', (req, socket, head) => {
    console.log('connect');
});

server.listen(5050, () => {
    console.log('listening');
});

And connect to it with curl curl -v --proxy 'http://127.0.0.1:5050' 'https://github.com'

What is the expected behavior?

Node:

$ node src/test.js
listening
connect

curl:

$ curl -v --proxy 'http://127.0.0.1:5050' 'https://github.com'
*   Trying 127.0.0.1:5050...
* Connected to 127.0.0.1 (127.0.0.1) port 5050
* CONNECT tunnel: HTTP/1.1 negotiated
* allocate connect buffer
* Establish HTTP proxy tunnel to github.com:443
> CONNECT github.com:443 HTTP/1.1
> Host: github.com:443
> User-Agent: curl/8.7.1
> Proxy-Connection: Keep-Alive
> 

What do you see instead?

Bun:

$ bun run src/test.ts
listening

curl:

curl -v --proxy 'http://127.0.0.1:5050' 'https://github.com'
*   Trying 127.0.0.1:5050...
* Connected to 127.0.0.1 (127.0.0.1) port 5050
* CONNECT tunnel: HTTP/1.1 negotiated
* allocate connect buffer
* Establish HTTP proxy tunnel to github.com:443
> CONNECT github.com:443 HTTP/1.1
> Host: github.com:443
> User-Agent: curl/8.7.1
> Proxy-Connection: Keep-Alive
> 
< HTTP/1.1 400 Bad Request
< Connection: close
< 
* CONNECT tunnel failed, response 400
* Closing connection
