Since in the above commit we converted integer site settings
to actual integers then set that as the new `buffered.value`,
the overridden indicator technically thinks the value has changed,
even if the user sets it back to the default:
```
overridden: propertyNotEqual("setting.default", "buffered.value"),
```
We can fix this by converting the parsed integer back to a string
before setting the buffered setting value.
