    dash: Make sure _clearDragPlaceholder() resets _dragPlaceholderPos
    
    The function currently only resets the placeholder position if
    there is a placeholder; this is not necessarily true, as the
    placeholder may be reset outside _clearDragPlaceholder().
    If this happens, the placeholder will temporarily stop working
    for the "old" position (and permanently if it's the only position).
    Just reset the position unconditionally.
