connectSlotsByName() misconnects slots when multiple children have the same name

I have a QWidget tree with two of them sharing the same object name (where widget_a is the top parent)

widget_a --- widget_b --- button1
      \--- button1

widget_a is an instance of a class which have a private slot named on_button1_clicked() connected by a call to onConnectSlotsByName().

At runtime on_button1_clicked() is not called when the user clicks on the button in widget_a but is called when the user clicks on the button in widget_b.

I think this behavior should at least be changed to give priority to the top most object. In the current situation, that means I could break an entire application by adding a widget in a window just because of a name collision (which I may not control if I happen to use a third party widget).
