TYPO3 Core

#93887 and #92406 introduced a new request handling for EXT:form forms. However, the new implementation hides the current ContentObjectRenderer instance since it always creates a new instance:

https://github.com/TYPO3/typo3/commit/9f933f2cf1c05709962c9efa2dd1951e7ad9a6a7#diff-4bbbe7629411df04b5f476caca764d500f1f55134e061c4533fe80bac36f9393R78

This no longer allows form finishers to retrieve the current content object data. For example, the current content object element ID is stored in EXT:form_consent when a new consent is created, see https://github.com/eliashaeussler/typo3-form-consent/blob/0.6.0/Classes/Domain/Factory/ConsentFactory.php#L121-L130.

Re-using the current ContentObjectRenderer via the ConfigurationManager solves the problem.
