TYPO3 Core

According to the documentation (https://docs.typo3.org/c/typo3/cms-form/main/en-us/I/Config/proto/formElements/formEditor/inspectorEditors/PropertyGridEditor.html)

If set to 'false' the column which is used to mark a row as preselected will be disabled.

However when I set this, nothing changes.

When I search TYPO3's source code, I find only documentation and configuration of this option, but no functional code, that does anything with it: https://github.com/search?q=repo:TYPO3/typo3+shouldShowPreselectedValueColumn&type=code

As a workaround I extended the PropertyGridEditor.html partial an hid the column with a style="display: none", because completely removing it breaks the JavaScript.
