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:

So fixing the typo allows to open the pdf but there is only 1 page when we have 9 in using masterpdfeditor.

    const numbers = this[$content]
      .trim()
      .split(/\s+/)
      .map(x => parseInt(x, 10));
    const ranges = [];
    for (let i = 0, ii = numbers.length; i < ii; i += 2) {
      ranges.push(numbers.slice(i, i + 2));
    }
    this[$content] = ranges;
