performance issue with Page::getCurentUrl()

[divinity76]

I recently have to write shit like

        $currentUrl = $page->evaluate('document.location.href')->getReturnValue();
        // don't use getCurrentUrl() because it has a performance issue... don't have time to investigate now

because when I write

        $t = microtime(true);
        $currentUrl = $page->getCurrentUrl();
        $t = microtime(true) - $t;
        echo "\ngetCurrentUrl() took {$t} seconds." . PHP_EOL;

i sometimes often get crazy readings like

getCurrentUrl() took 0.46461796760559 seconds.
getCurrentUrl() took 2.9382970333099 seconds.
getCurrentUrl() took 4.4821469783783 seconds.

but when I write

        $t = microtime(true);
        //$currentUrl = $page->getCurrentUrl();
        // don't use getCurrentUrl() because it has a performance issue... don't have time to investigate now
        $currentUrl = $page->evaluate('document.location.href')->getReturnValue();
        $t = microtime(true) - $t;
        echo "\ngetCurrentUrl() took {$t} seconds." . PHP_EOL;

I consistently get fast readings like

getCurrentUrl() took 0.00039219856262207 seconds.
getCurrentUrl() took 0.00027704238891602 seconds.
getCurrentUrl() took 0.00028014183044434 seconds.
getCurrentUrl() took 0.00026392936706543 seconds.
getCurrentUrl() took 0.00025701522827148 seconds.

Unable to share the actual script where it happens.

Tried making a simple reproduce script, but failed. This code does not reproduce the issue.

<?php

declare(strict_types=1);
require_once(__DIR__ . '/../composer/vendor/autoload.php');
$chromeBinary = "/snap/bin/chromium";
$browser_factory = new \HeadlessChromium\BrowserFactory($chromeBinary);
$browser_factory->setOptions([
    "headless" => true,
    "noSandbox" => true,
    'customFlags' => [
        // docker ...
        '--disable-dev-shm-usage',
    ]
]);
$browser = $browser_factory->createBrowser();
$page = $browser->createPage();
$highscore = -INF;
for ($i = 0; $i < 100; ++$i) {
    $page->navigate("http://example.com")->waitForNavigation();
    $t = microtime(true);
    $url = $page->getCurrentUrl();
    $time_taken = microtime(true) - $t;
    if ($time_taken > $highscore) {
        $highscore = $time_taken;
        echo "New highscore: {$highscore} seconds for getCurrentUrl() on {$url}" . PHP_EOL;
    }
    $page->navigate("http://example.org")->waitForNavigation();
    $t = microtime(true);
    $url = $page->getCurrentUrl();
    $time_taken = microtime(true) - $t;
    if ($time_taken > $highscore) {
        $highscore = $time_taken;
        echo "New highscore: {$highscore} seconds for getCurrentUrl() on {$url}" . PHP_EOL;
    }
