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 (typeof this[$content] === "string") {
      
      
      const html = valueToHtml(this[$content]).html;
      if (this[$content].includes("\u2029")) {
        
        
        html.name = "div";
        html.children = [];
        this[$content]
          .split("\u2029")
          .map(para =>
            
            
            para.split(/[\u2028\n]/).reduce((acc, line) => {
              acc.push(
                {
                  name: "span",
                  value: line,
                },
                {
                  name: "br",
                }
              );
              return acc;
            }, [])
