Drag attachment from inspector

I have a task that was created by forwarding an email to the omnisync server. This email and task have attachments. I can see the attachments in the inspector, but cannot drag them to a folder or to yoink for sending to a folder.

Is this how Omnifocus 2 is supposed to work?

Can you double click to open the attachment and then save them manually? Not ideal but could be an interim solution for you.
