Nested form fields validation doesn’t get triggered with triggerValidation or on change

[ghost]

Describe the bug
We are using nested form fields (e. g. "person.firstName") in combination with yup validation schemas. The validation gets triggered on onSubmit but it doesn’t work with triggerValidation(['person.firstName', ...]). triggerValidation('person.firstName') works but the validation doesn’t get triggered when changing the fields input value.

To Reproduce
Steps to reproduce the behavior:

1. Go to https://codesandbox.io/s/bold-murdock-pq8l2
2. Click on the button "triggerValidation(nested)
3. Open the console
4. See errors is still an empty object

Expected behavior
I would expect that triggerValidation works with an array with nested form field names an that onChange triggers a revalidation.
