react-hook-form: How to reset dirty or reinitialize form? dirty never false after call reset()

Describe the bug Dirty is not reset after call reset().

To Reproduce Here is codesandbox for reproduce: https://codesandbox.io/embed/smoosh-shape-fuy5e

1. There is SampleForm component to receive user and onSubmit props. it use useEffect() hook(line 15 ~ 18) for reset form when props.user is updated. but currently, I commented reset(user)(line 17) for reproduce.
2. change some fields, and reset original value. the submit button’s disabled is toggle via formState.dirty (ex> Update name to Foo1, submit is enabled. Update name to Foo, submit is disabled)
3. uncomment SampleForm line 17, reset(dirty) line. and try again step 2. the submit button is never disabled again even I tried set original value.

Expected behavior formState.dirty should be false when I change form value to original after call reset()
