fix: Action's Widget shouldn't show in some time

[18202781743]

DStanardAction's widget is not be repaint when the item moved to unvisual area, it causes widget is show in origin position. We manually hide those widget which in unvisual area before itemdelegate painting.

Log: DStandardAction设置了widget，在item移动到不显示的区域后，没有被重 绘,导致widget仍然显示，并且位置显示错误 Influence: 使用了DListView的应用，在item位置被移动后，原来位置仍然显示 之前的控件
