[Interest] CSS class only works in designer, not during runtime

[Philipp Kursawe]

Well, it seems these 3 lines solve the issue:

widget->style()->unpolish(widget);
widget->style()->polish(widget);
widget->update();

However this should be handled by the QWidget internally, when it knows
that a dynamic property is used in a style.
