    artistview: Avoid initial row activation selection
    
    On initial start the first row of ArtistsView is activated. If this
    occurs while another view is in selection mode, all items of the first
    row (artist) will be selected.
    
    Use Window's active-view property to check if ArtistView is the active
    view while a selection is being made.
