Reproduction steps
1. Receive a new message in DM, causing an unread notification dot to appear.
2. Open the DM chat and view or reply to the incoming message.
3. Go back to the DMs list and change to another chat.
4. Go back again to the chat you replied and check the behavior of the notification dot and the "NEW" marker inside the chat.
Expected behaviour
The unread notification dot and "NEW" message indicator should immediately clear and disappear once the user enters the chat, reads the messages, or sends a reply.
Actual behaviour
The notification indicator persists even after replying, sometimes marking the user's own reply as the "NEW" message, or remaining active indefinitely until restarting the app or waiting several seconds.
