Note

• When the user loads a specific PDF with XFA forms displayed in 2 columns, he will notice that headers from the second column are displayed on the first column.

Affected versions

• Nightly v91.0a1

Affected platforms

• all

Steps to reproduce

1. Launch browser.
2. Flip the pdfjs.enableXfa to true.
3. Load the attached PDF file.
4. observe the column headers.

Expected result

• The next page is displayed.

Actual result

• The headers from the second column are being displayed on the first.

Regression range

• Not a recent regression, but an implementation flaw.
• I have to mention that in Beta v90.0b6 and v90.0b8, 6 out of 7 pages are being displayed (compared to how Adobe Reader loads it), but most of the page elements are missing.

Might be the same root cause as bug 1718243.
