Multi-layered PDF is not displayed properly

[izolenta]

Link to PDF file : 17_BY400_PURL_working.pdf

Configuration:

• Chrome 56.0.2924.87 (64-bit) (also confirmed on Safari 10, FF 51.0.1 (64-bit))
• Ubuntu 16.10 (also confirmed on Mac Os Sierra)
• PDF.js version: any (confirmed on 1.7.348, 1.5.188)

Steps to reproduce the problem:

1. Open attached file in demo viewer at https://mozilla.github.io/pdf.js/web/viewer.html
2. Scroll to page 3 (important!)

What is the expected behavior?
Note that there is a layer with the gradient (diagonal stripes) at the top-right part of the page:

What went wrong?
No gradient layer is rendered

If I understand this correctly, the diagonal stripes and the gradient should be present on page 3 just like it is present on page 1. Am I correct ?

If I am, the issue still persists.
