I believe this is a bug.
When attempting to paste the following address into an address field (To, Cc, Bcc), it will not paste:
"Smith, John" <somebody@example.com>
Taking out the comma appears to allow pasting:
"Smith John" <somebody@example.com>
It seems to be an issue with the comma. My understanding, having experience with a lot of email applications, is that anything within the quotation marks for a “name” is supposed to be protected.
Another issue with pasting addresses is that a group of them cannot be pasted, when either delimited with a comma or semicolon.
"Smith John" <somebody1@example.com>, "Smith Frank" <somebody2@example.com>, "Smith Sam" <somebody3@example.com>
"Smith John" <somebody1@example.com>; "Smith Frank" <somebody2@example.com>; "Smith Sam" <somebody3@example.com>
Try either. They don’t work. They cannot be pasted.
Again, this is counter to expected conventional behavior.
Issues?
