issue: fields that use Controller or useController with its own defaultValue don't reset when resetField() is called after unmounting

Steps to reproduce

1. type in something to the input, ex: "asd"
2. click on "show results" (which will "unrender" / "unmount" the form)
3. click on "edit" (which will render the form again)
4. click on "reset field" (calls resetField("firstName"))

Expected behaviour

Results:

• the value in the input is still on "asd" when it should be set to undefined
• though the useForm() has the correct values, check the logs (which shows watch("firstName"), correctly showing undefined), although it should technically be the value of the defaultValue of the - which is another issue i think

Notes:

• when defaultValue is set with something, ex: useForm({ defaultValue: "" }), it does work properly
• setValue("firstName", "somethin") does work, click on "set value" to see

please provide defaultValues: useForm<FormInputs>({ defaultValues: {} }); resetField tries to get what's in the defautlValues but it's undefined with what you have provided.

yes adding defaultValues fixes it, but the default behavior is that when u dont have defaultValues in useForm() it uses the defaultValue of the Controller - which is how it works before the "underender" step, just not after it. rn behavior is not consistent.

and also, useForm() with empty defaultValues should have actually made it undefined right? its the default behavior - but its not updating it to that either

Is it correct that it hasn't been resolved?
