Description

There is an error in the EXT:form documentation:
https://docs.typo3.org/typo3cms/drafts/code.tritum.de/TYPO3.CMS/Form_Documentation/Concepts/Configuration/Index.html?highlight=null#inheritances

Finally, all configuration entries with a value of `null` are deleted.

It’s not `null` but `__UNSET`.

This is done in `TYPO3\CMS\Core\Utility\ArrayUtility::mergeRecursiveWithOverrule()` line 613:
https://github.com/TYPO3/TYPO3.CMS/blob/TYPO3_8-7/typo3/sysext/core/Classes/Utility/ArrayUtility.php#L613
