[Form_MGT-7.pdf](https://github.com/mozilla/pdf.js/files/6768253/Form_MGT-7.pdf)

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.

    if (this.name) {
      attributes.xfaName = this.name;

    const html = {
      name: "div",
      attributes,
      children: [],

    const bbox = computeBbox(this, html, availableSpace);
    const value = this.value ? this.value[$toHTML](availableSpace).html : null;
    if (value === null) {
      this.w = savedW;
      this.h = savedH;
      return HTMLResult.success(createWrapper(this, html), bbox);
    }
    html.children.push(value);
    if (value.attributes.class && value.attributes.class.includes("xfaRich")) {
      if (this.h === "") {
        style.height = "auto";
      }
      if (this.w === "") {
        style.width = "auto";
      }
      if (this.para) {
        
        
        attributes.style.display = "flex";
