As identified by @austinh in #13026 there are two sessions after authentication, since the previous session is migrated to a new one by
session_regenerate_id
. This PR ensures the old session is been deleted immediately on migration.I can't see any drawbacks, but if the change would break BC, another approach would be to add a new strategy like
switch
to enable instant deletion of the old session.
