The root cause is that BasicSpinnerUI forgot to reset the border in uninstallUI() by the LookAndFeel.uninstallBorder(). I have found one more place where the LookAndFeel.installBorder() is not followed by the LookAndFeel.uninstallBorder() in the AquaSpinnerUI.

The test will cover the old use case(headless) and the headful as well.
