... populated on submit

Are you seriously, maaan

That will don't guaranty that those fields are will actually be submitted. Because request can be initiated in some cases even before JS submit events, especially when fields filling still in process by even 0.xxx ms

Fill on change event, it will be 100% reliable.

You have a good library, but so many untested cases is ☠️
But I hope all will became good and those issues be resolved 🙏🏻👍
