No notification email when the user is mentioned

How is it now?

When someone mentions me in a circle, I don't get a notification email.

However I get emails for private messages. So I guess this is not linked to my email address being wrong or emails not being delivered.

How should it be?

I should get an email if someone mentions me in a circle.

Steps to reproduce

That's the tricky part... apparently I'm the only one in this case?

  1. Mention a user in a channel
  2. This user does not receive an email notification that this has happened
