Why @invalid-submit or :onInvalidSubmit props not working with submitForm?

[lbineau]

As stated in https://vee-validate.logaretm.com/v4/guide/components/handling-forms#handling-invalid-submissions

Specifying a onInvalidSubmit prop or @invalid-submit will run your handler if you submit your form using either handleSubmit or the regular form submit event but not the submitForm function.

The usecase is focusing the first invalid field, no matter if we use sync or async submission.
I don't understand why it doesn't work with submitForm. Is it technical issue?

How to make it work with submitForm?

Thank you.

Looks like a bug, I created an issue for it in #3841
