Viewing a DM with no messages doesn’t clear any notifications from there

Observed behaviour

The DM still shows you have messages unread until manually marked as read. Having any messages in the DM when viewing will not reproduce it, all messages must be deleted.

Reproduction steps

Receive a DM
Have the sender delete all messages in the DM.
