QDoubleSpinBox.setValue does not accept integers >= 2**63

from PySide6.QtWidgets import QApplication, QDoubleSpinBox

app = QApplication()
box = QDoubleSpinBox()

value = 2**63 - 1
# Works fine
box.setValue(value)
box.setMaximum(value)

value = 2**63
 # Workaround:
box.setValue(float(value))
box.setMaximum(float(value))

# OverflowError: int too big to convert
box.setValue(value)
box.setMaximum(value)
