TYPO3 Core

The check for composite form elements in the RenderAllFormValuesViewHelper is broken:

            if (
                !$element instanceof FormElementInterface
                || $element->getType() === 'Honeypot'
                || (
                    isset($renderingOptions['_isCompositeFormElement'])
                    && $renderingOptions['_isCompositeFormElement'] = true
                )
            ) {
                continue;
            }

This was implicitly fixed for master in #81770.
