An ordinary chat message answers the session's open ask in the user's
own words, so keeping the form open would invite answers to questions
the conversation has already moved past. The form now closes as
cancelled, browsers clear the live card, and the model is told without
being woken so the notice rides into the turn the message itself
starts. Ignored duplicate queued messages skip the void on purpose:
they must not void an ask posted after the queued original.
