Configuration:

• Web browser and its version: FF 83.0
• Operating system and its version: Windows 10 Pro
• PDF.js version: 2.7.99 / 2.7.295
• Is a browser extension: yes / no

Steps to reproduce the problem:

1. Open document Subscription-tekMag.pdf
2. See the wrong rendered appearances
3. Choose a subscription through the radio button group (Choose your Subscription)
4. Save the document (STRG+S)

What is the expected behavior?

What went wrong?

Also when the file is saved the AP dictionary has invalid data and the radio button groups are not useable anymore. E.g.:

/N << /2#20years,#2024#20issues#20(digital#20download#20only) 162 0 R>>

Looks like the name is not escaped correctly.

(The checkbox at the end has also a strange behavior (always locked when saved) - ping me, if I should open an additional issue for this one)

There is already a PR for this (see above).

The escaping is fixed by the PR above. Please open a new issue for any remaining issues so we have one problem per issue. Thanks.

Looks like the checkbox was fixed by the same PR. I guess that the appearances are not used is an already known/reported issue/known limitation?

[timvandermeij]

Ah yes, that would be #12234, so I think everything here is either fixed or tracked in that issue.
