Any React/Next wizard who can tell me why the setIsSubmitting state is not working here? I know you can use the new useFormStatus hook, but it would be nice to get this information directly in a hook like this.
My guess is that it has something to do with asynchronous code and batching, but I've been scratching my head too long at this to make any more sense of it. in the form.tsx file

Thanks!
