Recently I noticed that users with Safari 17 have some troubles using my website. I found out that the problem affects only users who use Safari in a private mode. After I dug deeper I realised that for some reason when I execute "window.location" for these users, query parameters do not present there even though they are actually present in the URL.
For example, user is on the URL
https://mywebsite.com/?code=TULEnfW1zRlqazI7XhM_QV7mxqPr-bV&state=5c5dbb2a-2332-4db7-a657-d2dc713d3e67
But the "window.location.search" returns an empty string.
Also, the issue is only reproduced when user is actually redirected to the "broken" page, but it works fine if the user opens the page in a new tab.
Issue is reproduced on both iOS and MacOS.
I have a suspicion that the issue is somehow related to the recently added feature which prevents cross-site tracking, however, disabling that feature did not help.
Does anyone aware of any recent changes to the behaviour of "window.location" in Safari?
Thanks!
