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.
const style = toStyle(this, "border", "font", "margin");
    const field = this[$getParent]()[$getParent]();
    const html = {
      name: "input",
      attributes: {
        type: "text",
        fieldId: field[$uid],
        dataId: field[$data] && field[$data][$uid],
        class: ["xfaTextfield"],
        style,
      },
    };
    return HTMLResult.success({
      name: "label",
      attributes: {
        class: ["xfaLabel"],
      },
      children: [html],
    });
  }
}
