useWatch getting re-rendered even if form values are not updated

[shahankit]

I created a simple form, and added useWatch for array field. FormProvider is wrapped with a component which calls API and passes it to FormProvider component. Is this expected that all watch fields of form will re-render if FormProvider is re-rendered?

In the above sandbox if you press UpdateResponse 1 button, it will re-render PassengersContainer as well.
