OJS 3.1.1.2: Email registration not complete but user shows up in list of Users

Hello,

We have enabled email registration in 3.1.1.2 but I am encountering unusual behaviour that I would like to clarify whether or not it is a bug.

A. I register for a test account with a journal using a yahoo address and the registration confirmation email is never received either in the Inbox or Spam.
B. I register for a test account with a journal using a gmail address and the registration confirmation email is received in the Inbox but I do not click on the confirmation link to complete registration.

In both cases, when I try to login using either account, I receive an error message as expected. However, when I login as Site Admin and look up the test accounts I created, both are listed as Users with the Reader role even though registration was never complete.

Is this expected behaviour or an error?

TIA,

Tara Stephens-Kyte
