Windows 11 Enterprise

Is the bug present in the latest PDF.js version?

Yes

Is a browser extension

No

Steps to reproduce the problem

1. Try to open the document in PDF.js.

What is the expected behavior?

In Adobe, a fillable form appears. On Chrome's PDF viewer, it displays a warning about Javascript not being enabled. Either would be preferable. With PDF.js, there's just a blank screen and an error in the log.

What went wrong?

There is an error in pdf.worker.mjs, in class PageSet, function $getNextPage. The code gets stuck in a loop where it sets this[$extra].pageIndex from 0 to -1, then from -1 to 0, and then back again.

A different error gets reported to the console. Chrome console:

Uncaught (in promise)
Object { message: can't access property "length", this.dims is undefined, name: "UnknownErrorException", details: TypeError: can't access property "length", this.dims is undefined, stack: "BaseExceptionClosure@https://mozilla.github.io/pdf.js/build/pdf.mjs:419:29\n@https://mozilla.github.io/pdf.js/build/pdf.mjs:422:2\n" }​

​​From XFAFactory.getNumPages(). But the reason that this.dims in undefined is the call stack error above.
