I have two problems.
The first is that when I am typing an email address, in this case when I am sending something to email@example.com, it converts to the iconified after the a after the @ before I can type the rest.
So it goes from msaroff@a to before I can type the x (or whatever)
Additionally, once it is in there as the iconified email address, I CANNOT EDIT IT.
I can delete, and attempt to retype the email (I literally need to enter in garbage to prevent the auto-complete until I am done), but I cannot edit the email once it is iconified.
I would note that I have a large number of msaroff@ email addresses, and I don’t mind it suggesting an alternative, but autocompleting to an UNEDITABLE email address is very real problem.
