QComboBox will emit currentIndexChanged when the index isn't changed

	QStandardItemModel model;
	model.appendRow(new QStandardItem("a"));
	model.appendRow(new QStandardItem("b"));

	QComboBox combo;
	combo.setModel(&model);
	QSignalSpy spy(&combo, QOverload<int>::of(&QComboBox::currentIndexChanged));

	combo.setCurrentIndex(-1);
	QCOMPARE(spy.count(), 1);

	//Setting it to the same thing shouldn't emit currentIndexChanged
	combo.setCurrentIndex(-1);
	QCOMPARE(spy.count(), 1);

	combo.setCurrentIndex(1);
	QCOMPARE(spy.count(), 2);

	//This will set "indexBeforeChange" to 1. It won't change until we update the model again
	model.appendRow(new QStandardItem("c"));

	combo.setCurrentIndex(-1);
	QCOMPARE(spy.count(), 3);

	//Because of QTBUG-103007 it will emit currentIndexChanged now. It didn't in QT5.
	combo.setCurrentIndex(-1);
	QCOMPARE(spy.count(), 3);
