UI bug causes no e-mails to be sent to CC, BCC and TO recipients

[markusweigelt]

Steps to reproduce

1. Type E-Mail addresses in TO, CC, BCC
2. Do not selecting the bubble with the mouse, only use tab to switch to next field or click direct in next field

Expected behavior

If you leave the TO, CC or BCC field, the mail must be selected automatically.

Actual behavior

This UI bug has caused a lot of confusion and the issue where emails were no longer forwarded to CC or BCC recipients. Sometimes, the TO recipients didn’t receive the email because they weren’t selected when only a CC recipient was chosen.
