 #!CommitTicketReference repository="" revision="61201"
 Mail: Improve multipart message handling in `wp_mail()`.

 This improves how `wp_mail()` handles `Content-Type` headers for multipart
 messages, preventing cases where the header could be duplicated.

 Developed in https://github.com/WordPress/wordpress-develop/pull/9500
