Parsing of `auth` differs from Node's behaviour

[pmmmwh]

Expected Behavior

When the username is empty and a password is available, the returned value of auth should align with output from Node's url module.

const url = require('url');
const nativeUrl = require('native-url');

url.parse('http://:[email protected]');
// { auth: ':password', ... }

nativeUrl.parse('http://:[email protected]');
// { auth: ':password', ... }

Actual Behavior

const url = require('url');
const nativeUrl = require('native-url');

url.parse('http://:[email protected]');
// { auth: ':password', ... }

nativeUrl.parse('http://:[email protected]');
// { auth: 'password', ... }

Steps to Reproduce the Problem

As described in code blocks above.

The culprit is this block, where all falsy values are filtered out.

I do think that this should technically be non-compliant with the spec (HTTP Basic Auth requires username to be defined) though ... ?
