1. Register to a Phabricator instance.
2. You will receive an email asking for verification. Do nothing about it.
3. Post a comment in a Maniphest task.
EXPECTED
Nothing happens in my mailbox until my email is verified. I could have typed a wrong email, I might be spamming someone else.
ACTUAL
Notifications start landing in your mailbox before any verification is completed.
Is this bad? Maybe not for the average user, but it is unusual, and not very professional.
