when mode is all，validate all fields but can's get all fields' errors in formState

[Hujianboo]

This is a relevant question. https://github.com/orgs/react-hook-form/discussions/11491
In brief, When I use useForm hook and mode is all ,Although every modification triggers a full validation, the "errors" in the "formState" only contain the fields corresponding to the currently focused component. I need to use watch and useEffect and then manually trigger. Is there any other better method?
