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.

      return HTMLResult.EMPTY;
    }
    const value = this.value[$toHTML](availableSpace).html;
    if (!value) {
      return HTMLResult.EMPTY;
    }
    const savedReserve = this.reserve;
    if (this.reserve <= 0) {
      const [w, h] = this[$getExtra](availableSpace);
      switch (this.placement) {
        case "left":
        case "right":
        case "inline":
          this.reserve = w;
          break;
        case "top":
        case "bottom":
          this.reserve = h;
          break;
      }
    }
    const children = [];
    if (typeof value === "string") {
      children.push({
        name: "#text",
        value,
      });
