SalesItemLineDetail.ServiceDate populates with undesired value

[EgorChernik]

I faced an unexpected behavior:
Invoice.Line[0..n].SalesItemLineDetail.ServiceDate obtains weird value "9999-12-31"

I'm using version 0.9.7
When I create an invoice using this library I don't specify any value in ServiceDate in my Line items.
And it creates without any issue and shows invoice in UI correctly

Magic happens when I update something (in my particular case Invoice.TxnTaxDetail.TxnTaxCodeRef.value)
It populates ServiceDate under the hood in all SalesItemLineDetail lines which I think is incorrect.

Can you try updating the Invoice.TxnTaxDetail.TxnTaxCodeRef.value through the API Explorer and see if it also populates the ServiceDate with "9999-12-31"?

Also, could you post example to reproduce the error?
