    conversation-view: Add hack to force TextView to wrap rather than grow
    
    GtkTextView's horizontal size request will grow over time
    when added to a GtkScrolledWindow with horizontal scrolling
    disabled, even when the TextView is set up to wrap lines.
    
    As a workaround, we overwrite its size request with a constant
    width to force the text to wrap around.
    
    See 65ce0de0e3abc9de4fd672c31a92120bf548c518 commit in polari.
