I am testing PDF.js Express version 8.1.1

**Detailed description of issue**  
I am testing the PDF.js Express in my [asp.net](http://asp.net) web application. We have pdfs with existing annotations but when they load I cannot see the annotations in the viewer.

**Expected behaviour**  
I would expect to see an icon with the annotation as I do when I open in Adobe or Chrome pdf viewer.

**Does your issue happen with every document, or just one?**  
Every document
