When I invite a non-user to a board with email address, it will invite an different existing user.

Repro: 

• Android App and Chrome/Firefox on Windows 10
• Open board>Members>Add Members>Type "namestartswithac@websitebeginswithay.org" & Add

Expected:

• Send an email to that exact address with a shareable link? 

Result:

• It adds user "@carlosbispa" or defaults to him straight away. I've tried dozens of differents ways to try to not highlight the user when it queries possible existing users before I click add, to no success. 

I will just add non-users to the board with a shareable link through email or text. It's strange because I can add users such as example@brandonphuong.net totally fine.
