    combobox: Also preselect active item in grid popup
    
    i.e. when wrap-width > 0. This was only being done for non-grid cases.
    So, ComboBoxes in grid mode did not indicate their selection when popped
    up and required users to keynav from ‘nothing’ (at the top-left) to the
    item they wanted to select. By selecting the active item in advance, now
    it’s highlighted & acts as the starting point for keynav around the grid
