    chatView: Fix updating compressed status message
    
    When updating the status group header, we delete all text until
    the end of the header tag before inserting the updated status
    summary. However this means that on the first update, we remove
    the newline between header and collapsed status message that is
    included by the tag - fix by deleting to the line end instead of
    the tag toggle.
