We need a form that displays all errors at the top hierarchy (error_bubbling = true) but at the same time allows to know whether an individual field has an error (to style it properly).
AFAIK, this is currently not possible. Because as soon as the errors bubble up, the form does not know about errors of individual fields. So maybe we can add a boolean marker to fields when an error is assigned to them so one knows about a field error even when the error bubbled up.
Or is there some way to achieve this with the current feature set? A workaround would probably be, to disable error_bubbling and manually collecting and rendering all errors.
