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 root = node[$getTemplateRoot]();
  let target = null;
  if (node.target) {
    target = root[$searchNode](node.target, node[$getParent]());
    target = target ? target[0] : target;
  }
  const { currentPageArea, currentContentArea } = root[$extra];
  if (node.targetType === "pageArea") {
    if (!(target instanceof PageArea)) {
      target = null;
    }
    if (node.startNew) {
      node[$extra].target = target || currentPageArea;
      return true;
    } else if (target && target !== currentPageArea) {
      node[$extra].target = target;
      return true;
    }
    return false;

    target = null;
