I created a pdf for https://github.com/mozilla/pdf.js/pull/14023:
[same_fields(1).pdf](https://github.com/mozilla/pdf.js/files/7168340/same_fields.1.pdf)
The 3 checkboxes have the same name (`Check Box2`) and have the same values (`Off` and `Yes`).
In pdf.js, these checkboxes behave like radio buttons in the same group (which is wrong) because of:
https://github.com/mozilla/pdf.js/commit/1fcffe80349a98378262c8a16f7b50ff34c3fe82
Since they've the same values they must be synced: if one is checked (resp. unchecked) then all others are checked (resp. unchecked).
this.downloadManager?.openOrDownloadData(
      this.container,
      this.content,
      this.filename
    );
  }
