    roomStack: Don't show entry area with placeholder
    
    With a visually distinct entry area, showing an insensitive entry with the
    placeholder helped reducing the visual noise during transitions.
    However now that the entry area appears as part of the chat log, it makes
    more sense to not show an entry when there is no chat log.
