The previous issue raised and marked as closed https://github.com/tweenjs/tween.js/issues/649 doesn't seem to be fixed. There is an open PR that fixes this, and just wanted to re-address it so it doesn't go under the radar 🙏 PR by @inukshuk: https://github.com/tweenjs/tween.js/pull/659
