Want to use QDateEdit with default SectionIndex set to the day. Index displays correct value, but the display and arrow keys respond as if it is still set to the default (month). Is this a bug or am I reading the documentation incorrectly? Extracted code:

python
import sys
import PyQt5.QtWidgets as qtw
import PyQt5.QtCore as qtc

class Window(qtw.QMainWindow):
    def __init__(self):
        super().__init__()
        self.setWindowTitle("QDateEdit")
        self.setGeometry(100, 100, 500, 400)

        self.dateEdit = qtw.QDateEdit(self, calendarPopup=True)
        self.dateEdit.setGeometry(100, 100, 150, 40)
        self.label1 = qtw.QLabel("", self)
        self.label1.setGeometry(100, 150, 200, 60)
        self.label2 = qtw.QLabel("", self)
        self.label2.setGeometry(100, 170, 200, 60)

        self.dateEdit.dateChanged.connect(lambda: self.dateChanged())
        self.dateEdit.setDate(qtc.QDate.currentDate())
        self.dateEdit.setDisplayFormat('MM-dd-yy')

        si = self.dateEdit.currentSectionIndex()
        print(f'default currentSectionIndex ({si})')

        self.dateEdit.setSelectedSection(qtw.QDateTimeEdit.DaySection)

        si = self.dateEdit.currentSectionIndex()
        print(f'after setSelectedSection.DaySection: currentSectionIndex({si})')
        self.show()

    def dateChanged(self):
        strDate = self.dateEdit.date().toString(qtc.Qt.ISODate)
        self.label1.setText(f'changed date({strDate})')
        si = self.dateEdit.currentSectionIndex()
        self.label2.setText(f'currentSectionIndex({si})')

App = qtw.QApplication([])
window = Window()
sys.exit(App.exec())
