Comment 7 for bug 1924832

Chromium-browser now incorrectly displays amounts in form fields that should be blank, in a file concatenated by PDFShuffler, from filled-in PDF forms saved from evince. Unsure whether the incompatibility arises from Evince, PDFShuffler, or Chromium. Note that on the file with the one form only (saved directly by Evince, not concatenated with others), Chromium correctly displays that form field blank.

File test-tax-cat0.pdf page 4, f1040 s2, Part I Tax, Line 1 AMT:

chromium-browser-106.0.5249.91: incorrectly displays, in lighter font, the number from page 3, f1040 s1, lines 1 and/or 14.
evince-3.36.10-0ubuntu1: correctly blank.
firefox-104: correctly blank.
xpdf-3.04-7: correctly blank.

Above describes the repro case I have on test-only data. The issue occurs with multiple form fields in another file that is confidential.

Currently running/testing chromium/evince/firefox/xpdf on Ubuntu-20.04.5/Linux-5.4.0/amd64.

The PDF files were generated in the original attempt to reproduce the issue, in 2021/04, on Ubuntu-18.04, same hardware:
