I occasionally incidentally see drafts by following our automated error-logging to the page where the error occurred, which could be the edit-post page, and in those cases I have looked enough to check things like whether it contains embeds, whether collaborative editing is turned on, etc. In those cases I try not to read the actual content. I don’t think I’ve ever stumbled onto a draft dramapost this way, but if I did I would treat it as confidential until it was published. (I wouldn’t do this with a DM.)
