`createButton` isn't passing user props to the element

[thetarnav]

User props such as class or children aren't being passed down to returned buttonProps.
The button doesn't seem clickable with Enter too..

export const Button: ParentComponent<
  JSX.IntrinsicElements['button'] & AriaButtonProps
> = props => {
  let ref!: HTMLButtonElement
  const { buttonProps } = createButton(props, () => ref)

  return <button {...buttonProps} ref={ref} />
};

// class and children aren't being applied
<Button class="btn">Hello</Button>
