    The 'Parent' is the control wrapping the containing window.
    The 'Owner' is the object responsible for object lifetime.

    When you destroy the parent, children are expected to be left parentless
    but still alive. Not so, they're also destroyed. The controls are worth
    little without a parent window, so manual handling would be needed
    anyway. If you do not want the children to be destroyed, you need to
    remove them before parent destruction.
