commit 935ea8098a9f9db5a86690eb48a28da929839d3a

    search: Set min-content-height on the scrolled window
    
    Set a minimum content height of 490px for the panel when the
    allocated height is smaller than 490px.
    
    490 is an estimated value for the panels to properly fit on netbook
    screens. See https://wiki.gnome.org/Design/SystemSettings#Notes
