Research direction

Start by locating the Angular ValidationErrorComponent and the abp-modal form flow described in the reproduction steps. Reproduce the error with a required field, then hide and show the field while watching the browser console. Done means the form can be opened, the validation error triggered, and the field toggled without ExpressionChangedAfterItHasBeenCheckedError.
