Session timeout expiry does not always expire the session

[martyf]

Bug description

Sometimes it does... but sometimes it doesn't.

Especially if the window is in focus during the timeout, I've noticed that the session can "expire" but then it doesn't actually really expire and renews. Like here it expires, asks for password, expires, then goes back to the CP with no user interaction at all - so it's not actually logged the user out.

How to reproduce

1. Statamic alpha 8
2. Create a user (mine has two factor - not sure if that matters)
3. Set SESSION_LIFETIME to 2
4. Log in, and wait 1 minute - the timeout modal appears, then wait another minute, and it can sometimes automatically renew the session

Looks like this is how it works on v5 as well (the modal you're seeing is the new version of the red banner):

That would mean this issue is applicable to both 5 and 6 then: when that password box appears, I should not be able to continue using the CP without the password.

But having it automatically keep you logged in for another session lifetime defeats the purpose of presenting the password box.

Either needs to actually log the user out, or stay on the password modal to allow the user to re-auth to re-extend the session: not automatically do it.
