Conflict with Ubercart setting 'Login users when new customer accounts are created at checkout.'

Issue Summary

If Ubercart its 'Login users when new customer accounts are created at checkout.' is disabled and Drupal core its 'Require e-mail verification when a visitor creates an account' is disabled: Email Registration still logs in the user, despite the Ubercart settings says not to...

My workaround: enable the 'Require e-mail verification when a visitor creates an account' setting.

But maybe Ubercart should use Drupal core's settings to determine if logging in after a new account has been created?
