Broken redirection in case of multiple external agents

Describe the bug
My app opens login page on browser for user authentication, and if browser also use his own external user agent (some card reader app) instead of username and password then last external user agent will not redirect connection back to app's browser but will create new instance of browser separated from app and redirect there. If browser doesn't use his own external agent but login with username and password then redirection is not broken and result is sent back to my app.

To Reproduce
Steps to reproduce the behavior:

1. Start a OIDExternalUserAgentSession, using for example: OIDAuthState.authState(...)
2. Browser login page must have additional authentication methods besides the username and password used by external applications.
3. On login page use another authentication method that use own external user agent
4. Second external user agent returns result to new instance of browser, insted of external user agent

Expected behavior
Redirection goes back to root app

Environment

• Device: iPhone 13
• OS: 18.5
• Browser: Safari

Additional context
/

Start with the OIDExternalUserAgentSession flow initiated through OIDAuthState.authState(...) and reproduce the behavior on iPhone 13 with Safari when a second external authentication method opens its own user agent. Done means the authentication result redirects back to the root app rather than a separate browser instance.
