Using fetch with proxy fails with ssl error

What version of Bun is running?

1.1.20+ae1948925

What platform is your computer?

Linux 6.6.36.3-microsoft-standard-WSL2 x86_64 x86_64

What steps can reproduce the bug?

Use bun fetch like this:

await fetch(url, {
      proxy: `https://${proxy.user}:${proxy.password}@${proxy.url}:${proxy.port}`,
      headers
    });

What is the expected behavior?

same as with node-fetch if i pass in the following format:

const proxyAgent = new HttpsProxyAgent(`https:https://${proxy.user}:${proxy.password}@${proxy.url}:${proxy.port}`);
await fetch(url, {
      agent: proxyAgent,
      headers,
    });

requests completes successfully.

What do you see instead?

SSL: SSL fetching "https://www.amazon.com/s?k=mx%20master%203s". For more information, pass verbose: true in the second argument to fetch()

Additional information

I'm using an https proxy from bright data for data centers. looks like this:

PROXY_URL=brd.superproxy.io
PROXY_USER=user-zone-datacenter_proxy1
PROXY_PORT=22225
PROXY_PASSWORD=somepass

here is the output using verbose: true:
