[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:

So fixing the typo allows to open the pdf but there is only 1 page when we have 9 in using masterpdfeditor.
