SelectButton: Submit with React Hook Form

[melloware]

Describe the bug

Same as: #3645

Forum Post: https://forum.primefaces.org/viewtopic.php?f=57&t=78159

When using SelectButton component with React Hook Form, on submit, if the password is the only field to fail validation then React Hook Form attempts to put a focus on the field but cannot and throws an error.

PrimeReact version

React version

Language

TypeScript

Build / Runtime

Create React App (CRA)

Browser(s)

ALL

Steps to reproduce the behavior

Create a react hook form with at least one PrimeReact Password component (form can have other fields/inputs too).
Make sure the PrimeReact Password component has some kind of validation - for example, field is required.
Fill in all fields, except for the PrimeReact Password (or otherwise make this field invalid)
Submit the form to see e.focus / elm.focus error.

Expected behavior

With all other fields types, standard html text or password, PrimeReact InputText then when submitting the form, if there are errors the first field with an error is focused on.
I would expect that, if the PrimeReact SelectButton component is the first invalid field then the form should focus on this field too.
