lokit: fix validation dropdown's wrong position

Reverse the zoom scale on the position of the dropdown before
letting the vcl::FloatingWindow convert this to twips without
any scale information. Without this reverse scaling, the
dropdown will be incorrect due to double application of the same zoom
(one in core and one in client).
