getPostingTransactionSummary Returns Item that does not Exist

For NetSuite Canada where Tax for Accounts Payable is available (such as Tax on Vendor Bill record), getPostingTransactionSummary may receive response that references a Tax Group as an Item on <platformCore:item />.

Take the below response on a getPostingTransactionSummary call:

Note that <platformCore:item internalId="84" /> is not an Item record in NetSuite, but rather, a Tax Group that can be found via Setup>Accounting>Tax Groups path.

Defect #234274 currently tracked this issue where a Tax Group is being referenced as an Item on the getPostingTransactionSummary response.
