Bug description

Settings --> Keyboard remembers key repetition and repetition speed only until the first reboot

Steps to reproduce

1. Open Settings --> Keyboard.
2. Set the two "repeat" & "delay" sliders to whatever lengths you want. Test them and remember the speed.
3. Reboot the computer then open anything with a text box, press and hold any letter key. Observe that "repeat" & "delay" are much slower than what you have set. It's like they've gone back to some kind of default values.

Expected behavior

When the "repeat" & "delay" sliders are pulled to whatever desired values, they should be remembered even after computer reboot.

Additional information

There's a workaround to that problem. Open Keyboard settings and move the "repeat delay" slider one step to the left or to the right and then return it back to the desired position. That restores the user values.
I tried saving the values in dconf-editor and restoring them with the dump command but that doesn't seem to help. Only manually moving the slider fixes the bug.

In case it matters:
GPU Driver - 550.67, kernel 6.6.28-2-LTS.

Start in Settings → Keyboard and reproduce the problem by changing the repeat and delay sliders, rebooting, and checking a text box. Trace how these values are saved and restored, using the reported dconf behavior as context. Done means the selected repeat and delay values remain effective after reboot, with regression coverage if the relevant test area is found.
