RT 6.0.2 - Attachment does not carry over if attached before selecting an article

Good morning,

I have had and verified a report from one of my end users regarding an issue with attachments not keeping when using Articles.

As the title suggests, if the end user attaches a file and then afterwards selects an article, then sends the ticket, the ticket no longer has that file attached either in RT or the correspondence sent to the user. However, if the user selects the article first, then selects the attachment, then sends the correspondence, the attachment goes through okay.

This is aberrant behaviour although with a simple workaround. The annoying part is the attachment still appears in the small text list implying it is attached, but it does not appear in the large box underneath the text editor - find below; only attachments in the big box here end up attaching correctly.

Hope this makes sense, let me know if any further details are required.

Kind regards,

Luna
