Appearance schedule resets after switch to dark mode

[wpkelso]

What Happened?

After setting the "Schedule" option in the appearance tab to "Sunset to Sunrise," the Sunset switch functions normally, but at some point the Schedule option gets switched back to "Disabled" and thus Sunrise does not trigger any switch of styles

Steps to Reproduce

1. System Settings > Desktop > Appearance
2. Set "Schedule" to "Sunset to Sunrise"
3. Observe switch at or after sunset
4. Suspend/Sleep/etc. overnight (haven't tested with shutdown)
5. Style should still be dark after sunrise, and "Schedule" should be disabled

Expected Behavior

Setting doesn't disable itself, and style switches normally

It appears this does not happen immediately upon switch; if the switch occurs while the device is on and unlocked the option is not reset.

Suspend/Sleep/etc. overnight (haven't tested with shutdown)

Seems to happen after shutdown, too.
