Bug report
What is the current behavior?
If keepDirtyOnReinitialize is true, when a field is changed from its initial value to undefined, the initialize logic will set formState.values to undefined which causes the form to crash.
What is the expected behavior?
formState.values should never become undefined. If a field's value is changed to undefined, the key should be removed from formState.values.
