Metadata. Including whether or not a message is junk mail, is trusted,

Research direction
Start by reproducing the issue with a Fastmail account using Mail app 1.13.4, then trace how IMAP metadata is represented and displayed as tags. No file or test is named; done means Fastmail metadata such as junk or trust status is no longer shown as user-created tags, with regression coverage added.
