[17.0] mail_tracking: Cc/Bcc not tracked when followers are disabled (with mail_disable_follower_notification)

[melissalateb]

Module

mail_tracking

Describe the bug

When using mail_tracking in combination with modules that disable follower behavior (e.g. mail_disable_follower_notification they alter message flow), Cc and Bcc recipients added via mail_compose_cc_bcc are not tracked at all in the mail.tracking.email model.

To Reproduce

Affected versions: 17.0

Steps to reproduce the behavior:

1. Install mail_tracking, mail_compose_cc_bcc, and mail_disable_follower_notification
2. Compose a message with recipients in Cc or Bcc
3. Enable "Disable Followers Notification"
4. Send the message

Expected behavior
Even if followers are disabled, Cc and Bcc recipients should be tracked by mail_tracking, since they are explicitly selected by the sender and should be auditable.

Additional context
With disabled followers notification

Without disabled followers notification
