I can't see the diagram you mentioned, but I think it is still possible to make a connection with the vertical ground plane using a wide metal sheet as sketched in Figure E.2 of CISPR 16-2-1:2008. Alternatively, if you wish to connect the LISN to the ground plane under the LISN, maybe you can screw a L-shaped metal sheet, which covers side and bottom surface of the LISN, to the side plate.
