Breaking: #82252 - Override TypoScript configuration formDefinitionOverrides by FlexForms

See forge#82252

Description

Override TypoScript configuration formDefinitionOverrides by FlexForms configuration.

Impact

Before this, FlexForm configuration of form was overridden by TypoScript formDefinitionOverrides, which is not the intended behaviour. Now the FlexForm configuration overrides the TypoScript configuration of the formDefinitionOverrides. This means, having a configuration of form in FlexForms and TypoScript, the form will change its behavior and start using the configuration defined in your FlexForm.

Affected Installations

All installations using the form framework and TypoScript/ FlexForm overrides are affected.
