Configuration:
- Web browser and its version: Firefox 84.0 (64 bits)
- Operating system and its version: Arch Linux
- PDF.js version: 2.7.262 (built-in) and 2.7.434 (development version at time of writing)
- Is a browser extension: no

Steps to reproduce the problem:
1. Open the linked PDF file linked above.
2. Notice that the first page is rendered completely broken. There are no warnings/errors in the console unfortunately, and it's not related to layers since the document does not contain any.

What is the expected behavior? (add screenshot)
