Are PDFs in iBooks supposed to be backed up to the cloud? I recently had to restore my iPad from a recent iCloud backup (after stupidly deleting my entire calendar by accident, long story) and when I restored, the PDFs I had stored in my iBooks app didn't come back. It's not a horrible thing, since there weren't too many and I still have them on my iPhone and Mac, but still kind of annoying. Am I missing some obvious setting here, or are they really not included in iCloud backups? For what it's worth, iCloud does sync things like highlights and the last page read between them, so I know it recognizes they're there...
