Pretty straightforward backport if we wanted to fix this in 106 still. I've verified that the PDF linked from the upstream issue renders correctly with the below Try build.

I have reproduced this issue using Firefox 107.0a1 (2022-10-10) on Win 10 x64.
I can confirm this issue is fixed, I verified using latest nightly Firefox 107.0a1 (2022-10-11) on Windows 10 x64, Ubuntu 22 and macOS 12, the PDF document shows the expected "Check Box" label.

The patch landed in nightly and beta is affected.
:Snuffleupagus, is this bug important enough to require an uplift?

• If yes, please nominate the patch for beta approval.
• If no, please set status-firefox106 to wontfix.

The patch is already nominated for uplift. The bot didn't realize it because it's nominated for release.
