Descrizione
What you were expecting: I would expect that useWatch returns the default value of the field.
What happened instead: useWatch returns undefined, untill I change the watched field.
Steps to reproduce:
create a form with an input that has a default value, then have another component use useWatch on that input field, the resulting value is undefined untill you change the input.
Related code: I created a WatchBug component in the PostCreate file. It watches the Published at input. you see that initally the value returned is undefined. https://stackblitz.com/edit/github-mjvobu?file=src%2Fposts%2FPostCreate.tsx
