not releases yet - but 6.4 - but 6.3.next

Description

This PR introduced a BC break : #52579

script:

#!/usr/bin/env php
<?php

require __DIR__ . '/src/Symfony/Component/DomCrawler/vendor/autoload.php';

$ret =  Symfony\Component\DomCrawler\UriResolver::resolve('https://', 'https://jolicode.com/');

echo "$ret\n";

Before:

On 0a30c9b (direct parent)

php test.php 
https://

After

on 89009aa:

$ php test.php 
https://jolicode.com/https://

How does a browser react?

Note: on a webpage, if I put <a href="http://">test</a>, and I click on it, I'll land on about:blank#blocked (at least in chrome), not on https://jolicode.com/https://

Some context

On seriously malformed URLs, parse_url() may return false.
(from https://www.php.net/manual/en/function.parse-url.php)

and

$t = [
    'http://jolicode.com',
    'http://',
    'foobar',
    '/bar',
    '/bar:1',
];

foreach ($t as $uri) {
    $o[$uri] = parse_url($uri, \PHP_URL_SCHEME);
}

dump($o);

returns

$ ./test.php
^ array:5 [
  "http://jolicode.com" => "http"
  "http://" => false
  "foobar" => null
  "/bar" => null
  "/bar:1" => false
]
