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 left = measureToString(this.x);
    const top = measureToString(this.y);
    const style = {
      left,
      top,
      width: measureToString(this.w),
      height: measureToString(this.h),
    };
    const classNames = ["xfaContentarea"];
    if (isPrintOnly(this)) {
      classNames.push("xfaPrintOnly");
    }
    return HTMLResult.success({
      name: "div",
      children: [],
      attributes: {
        style,
        class: classNames,
        id: this[$uid],
      },
    });
  }
}
