Why is my QPalette not replaced at sunset?

My Configuration

My Environment

Operating System: Fedora Linux 43
KDE Plasma Version: 6.5.5
KDE Frameworks Version: 6.22.0
Qt Version: 6.10.1
Kernel Version: 6.18.7-200.fc43.x86_64 (64-bit)
Graphics Platform: Wayland

It was replaced, at T17:24:08+00:00. I don’t understand why it delayed this PT1H past what it accurately considers to be sunset, considering that AOSP 15 does not.
