SUMMARY

In the "Battery and Brightness" applet, after unchecking the "Inhibit automatic sleep and screen locking" checkbox, the power management inhibition remains active. Only restarting plasmashell resets all inhibitions.

I found, that after unchecking the above checkbox, PlasmaCore.DataSource for the "powermanagement" engine still contains the "plasmashell" inhibition (https://invent.kde.org/plasma/plasma-workspace/-/blob/master/applets/batterymonitor/package/contents/ui/logic.js#L77).

STEPS TO REPRODUCE

1. Open "System Settings"
2. Go to "Power Management" > "Energy Saving"
3. Check "Dim screen" checkbox and set delay to 1 minute
4. Open "Battery and Brightness" applet
5. Check the "Inhibit automatic sleep and screen locking" checkbox to enable power management inhibition and wait a few seconds (it takes a few seconds to turn it on)
6. Uncheck the above checkbox to disable power management inhibition
7. Wait 1 minute until the screen goes dim

OBSERVED RESULT

The screen doesn't dim.

EXPECTED RESULT

The screen dims.

I have the same problem with the battery and brightness widget on the panel. Once you uncheck the setting, you cannot re-enable automatic sleep and screen locking by simply re-checking the setting. You must also restart the plasma shell by logging out and logging back in.
