Deleting an unread message does not reduce the unread_messages count

[jhwheeler]

When a user sends a message, the unread_messages count for the other user in the channel increments, as expected; however, if the first user then deletes that message (with the hard_delete option) before the other user has read it, the unread messages count does not go back down, but stays incremented.

I am getting the unread messages count from channel.state.read[current_user].unread_messages. Perhaps I am looking in the wrong place?
