    [WINESYNC][COMCTL32] Listview: Initialize marqueeRect from left-click coordinates
before starting a marquee highlight (#5555)
    
    The infoPtr->marqueeRect structure is not currently initialized before the
    marquee highlight sequence starts, resulting in the RECT having initial
    coordinates of (0,0)-(0,0). These coordinates cause the first item in
    the listview control to be identified as being within the range of the
    marqueeRect's coordinates.
    
    That item is then set to LVIS_SELECTED even though it is not part of the
    marquee selection.
