File references in playlists do not match directly after create

Not sure if it is a bug, but it is at least misleading, so I'd change it, if it is not a big effort:

When I add a playlist and reference an existing file, the playlist is created but in the response body the content of the playlist entry representing the file does not match the file. It seems as if only the id is added and otherwise it looks like a new file. But when I then fetch the playlists via get, everything is fine.

See the following screenshots.
