This is not a bug, this is how the hardware works, you need some kind a program
with does reapply that value at boot. They is no way for the kernel to make it
persistent just because the hardware doesn't support persisted charger limit.
Most users on ASUS laptops use asusctl for that:
https://gitlab.com/asus-linux/asusctl it works on TUF laptops too and charger
limit control should work on ZenBooks too, you only need to manually add
asusd-alt service and enable it

So, if KDE Plasma has a feature that allows you to set a battery charge limit,
it's up to them to re-set it on every boot, right?
