Safari doesn't redirect to a different domain

Hi. I'm developing a widget that, in certain cases, needs to redirect the user to a different domain. For example, when I open https://premium.onet.pl/ and then, through the developer console, execute a redirection such as:

  window.location.href = "https://google.com"

nothing happens in Safari (Version 18.3.1). In contrast, the same redirection works flawlessly in Chrome.

I have experimented with several methods, including:

window.location.href = "https://google.com"
setTimeout(() => { window.location.href = "https://google.com" }, 250)
window.location.assign("https://google.com")

I also disabled the Website Tracking option in Safari's Privacy tab, but the issue persists.

In browser's incognito mode the issue persist

Here are some relevant header details from the request to https://premium.onet.pl/:

I found an article (https://stackoverflow.com/questions/79390056/safari-not-redirecting-using-window-location-replace-or-window-location-href-on#:~:text=Safari%20has%20ITP%20(Intelligent%20Tracking,location) on StackOverflow indicating that Safari's Intelligent Tracking Prevention (ITP) might be interfering with redirects. Could you please confirm if ITP is the cause of this behaviour? If so, is there any supported way to disable ITP for redirection purposes?

Any guidance you can provide would be greatly appreciated.

Thank you for your assistance.
