Description

Reproduce¶

Configure a simple text input field ('type' => 'input') in TCA to allow null values ('eval' => 'null')

Result¶

A checkbox "Set value" to allow null values is shown in the backend as expected.
However, once you uncheck this checkbox, it becomes permanently disabled and you cannot re-check it.

Expected behaviour¶

The unchecked checkbox should be clickable so that you can check it again.
This worked fine in Typo3 10, and stopped working with Typo3 11.
