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.
constructor(attributes) {
    super(TEMPLATE_NS_ID, "checkButton",  true);
    this.id = attributes.id || "";
    this.mark = getStringOption(attributes.mark, [
      "default",
      "check",
      "circle",
      "cross",
      "diamond",
      "square",
      "star",
    ]);
    this.shape = getStringOption(attributes.shape, ["square", "round"]);
    this.size = getMeasurement(attributes.size, "10pt");
    this.use = attributes.use || "";
    this.usehref = attributes.usehref || "";
    this.border = null;
    this.extras = null;
    this.margin = null;
  }
