The sidebar shows every DM's online/offline dot at once, but the only existing signal for a presence change (member_updated) is broadcast to a room's own channel, which Presence only delivers to a connection that currently has that specific room joined -- never true for a DM sitting unopened in the sidebar. Add a dedicated per-user broadcast (dm_presence_update) sent to each of a user's DM partners on their own per-user channel whenever their global online/offline state changes, so the sidebar dot updates without needing that DM to be the open room.
