Attachment in email replies do not attach to a transferred case - Known Error

Attachment in email replies do not attach to a transferred case Description Incoming emails matched via watermark to a case that has since been transferred will attach to the original case only to the activities and not to the attachment list in the top of the page.

Steps to Reproduce

Set up emails on the instance and set the 'sn_hr_core.hr_email' property to the expected email address. As a user, send an extrenal email to the system with an attachment file The email will create a hr case with one attached (example: HRC0008647 was created) As the HR Agent assigned to the case (or HR Admin), transfer the case, with the same number, to a different HR Service. A new case is created HRC0008648 As the HR Agent, add a comment to the new case - this will send a notification to the user As the user, reply on the notification and attach an attachment

Actual behavior: The attached file is added to the activities and not in the attachment list for HRC0008647

Expected behavior : The attached file should be in the header in the attachment list and activities Workaround This is expected behavior and by design in all currently supported releases.
