When we try to open the above pdf, we get in the console:
```
Warning: XFA - an error occured during parsing and binding: TypeError: x.include is not a function
```
which is caused by a typo:
https://github.com/mozilla/pdf.js/blob/b9e84ba70ec5a4a30333b9092f316c9ec7b7f079/src/core/xfa/config.js#L174
 
So fixing the typo allows to open the pdf but there is only 1 page when we have 9 in using masterpdfeditor.

      type = "checkbox";
      className = "xfaCheckbox";
      dataId = field[$data] && field[$data][$uid];
    }
    const input = {
      name: "input",
      attributes: {
        class: [className],
        style,
        fieldId,
        dataId,
        type,
        checked,
        xfaOn: exportedValue.on,
      },
    };
    if (groupId) {
      input.attributes.name = groupId;
    }
    return HTMLResult.success({
      name: "label",
      attributes: {
        class: ["xfaLabel"],
      },
      children: [input],
    });
  }
}
