Session Cookie in Blazor Interactive Rendermode and individual Identity with Default Web APP

I made a Blazor 8 Web app project with Interactive Server, individual Identity, per page/component.

1. so I just did debug it

2. registered one user

3. and login

4. close the tab or close the web browser each time

5. but the session cookie is still alive

Why does Blazor work like this, in default mode?

Even though I tried to put some more options in 'program.cs' it is not changed at all.

I want the session cookie to expire when I close the tab or the web browser. And Shouldn't it be the default practice like that?
