 When using `register_setting()` and providing a 'default' value, that
 value is set as the default for `get_option()` calls using a filter.
 However, when using `unregister_setting()` for such a setting, the filter
 hook is not removed again. This seems like an oversight and should be
 fixed.

 For reference, the functionality was introduced in [38910].
