PO Print PDF does not show correct line item revision while PO requires re-approval or is being rout

This is related to Bug 8720405 - https://support.oracle.com/epmos/faces/BugDisplay?_afrLoop=239225258812092&id=8720405&_afrWindowMode=0&_adf.ctrl-state=xfe96a4or_49 created in 2009 but still existing as a but in 12.2.7

The Buyer Work Bench > Orders > any revised order > View PDF option will display the previous revision number against line items until the current revision is approved.

Steps to recreate:

Create a Simple PO with Line 1, Qty 1, Unit Price $10000.

Approve the PO.

Update the PO and change the Qty to 2.

View PDF

The PDF will show the PO as Rev 1 but the Line Item will still say Rev 0 while showing the revised Qty and Extended Price. This is extremely misleading and results in a lot of confusion on large POs with hundreds of line items of which a relatively small percentage may have changed Buyers need to be able to be able to review the PO and see the changes BEFORE submitting for approval and that is most easily done using the View PDF option.
