[4.0.0] The `value` prop supplied to <select> must be an array if `multiple` is true.

I'm not sure if I'm doing something wrong, but since the bump I'm getting that error when using a <select multiple> component with a name that contains a path to an array.

The name passed to Field is roles[${idx}].scopes and I made sure that there is indeed an array inside of scopes.

Ah, I figured it out.

This fails:

<Field<StaffFormRole['scopes']> name={`roles[${idx}].scopes`} validate={required} type="select">
	{({ input }) => (
		<Select id={input.name} {...input} multiple>
			...
		</Select>
	)}
</Field>

This does not:

<Field<StaffFormRole['scopes']> name={`roles[${idx}].scopes`} validate={required} type="select">
	{({ input: { value, ...input } }) => (
		<Select id={input.name} value={value || []} {...input} multiple>
			...
		</Select>
	)}
</Field>

Should the library just handle undefined as a default [] for value?
