for those of you looking for a way around this. I was able to get this to work:

class CustomModal extends Modal {
  render(): React.ReactNode {
    // eslint-disable-next-line react/jsx-props-no-spreading
    return <Modal {...this.props} animationType="fade" />
  }
}

<Tooltip
   modalComponent={CustomModal}
>

Seems simple enough, let's change the defaultProp and we are good to go

the current default is 'none' could you update this so it is backward compatible?
