Not fixed in Beta 5.

I don't think that it's related to UITableView: I've created a very basic implementation where the primary view controller is a SwiftUI List and embedded it in a UIHostingController, but get the same outcome.

Turns out we still do have a problem with iOS 15.5 (beta 4). We fix the associated domain issue, it works work well from outside and inside the app on iOS 15.4, but on iOS 15.5 it only works from the outside, not within ASWebAuthenticationSession or SFSafariViewController.
