how ejabberd handle when client-A's Network down after composing message sent

This query is related to typing indication.
Client-A send composing message to client-B. So, Client-B will understand Client-A is typing a message.
before sending pause message, Client-A's network goes down and assume that it's network never be up. In this case client-B will never receive pause or inactive message from client-A and it continuously display 'is typing...'.
My question is:
1. How ejabberd server handle this case?
2. Can ejabberd send inactive/pause behalf of Client-A?

Thanks in Advance...
