/**
 * A `Form` component that takes a `name` prop. Functions exactly like a normal
 * Form, except that when a `name` is present it will defer errors up to the parent `<Form>`,
 * functioning like a `<Form.Field>`.
 *
 * This is useful for encapsulating complex input groups into self-contained
 * forms without having to worry about `"very.long[1].paths[4].to.fields"` for names.
