Comment (by gcorne):

 In [attachment:29304-01.patch 29304-01.patch], I believe that I have fixed
 the issue. The main issue is that there are multiple instances of the
 {{{media.view.Attachments}}} view in the modal. It is used in both the
 {{{AttachmentsBrowser}}} and via inheritance in
 {{{Attachments.Selection}}} which meant that the keyboard event was firing
 twice and the last one was in the context of the selection instance which
 wasn't the desired behavior. I also added a check to use the current
 selection if there were no focused list items.
