Symptoms

In the Payables Invoice Workbench's Tax Line form, after updating the tax rate on the existing line so that a new tax line is created with the new tax rate, the Cancel flag stamps on the new tax line instead of the old tax line.

Actual behaviour
After changing the tax rate on a PO-matched invoice from 'GST10 % AP' to 'GST FREE AP', the Cancel flag is stamped upon the 'GST FREE AP' tax line.
The Tax Calculation is still correct, but this presents a tax reporting problem.

Expected behaviour
The Cancel flag should be stamped upon the 'GST10 % AP' tax line, the line showing the original tax info.

The issue does not reproduce for non-PO matched invoices.

Steps to reproduce
1 - Create a PO with tax 'GST10 % AP'
2 - Create an invoice, and match to the PO
3 - Change the tax line: update the rate from 'GST10 % AP' to 'GST FREE AP'
4 - The Cancel flag is stamped against the 'GST FREE AP' tax line; this should be the 'GST10 % AP' line.
