Replies you watch arrive are no longer marked as new

Until now, an agent's reply that arrived while you had its conversation open still got the orange "new" edge, as if you had missed it. Now a message that arrives while the conversation is open and the page is in view counts as read and gets no edge. Messages from before you opened the conversation, and those that arrive while the page is hidden (another tab, a locked screen), are still marked as new. Obeya's own chat sheet works the same way now: an answer that arrives while the sheet is open is read, without the edge.
