Strangely, the shipped Cairo of Mozilla Firefox seems to be used instead of the system Cairo package at version 1.16.0-5.
Expected results:
The resulting PDF should be much smaller. Brave creates a 541 kB PDF file.

The Bugbug bot thinks this bug should belong to the 'Firefox::PDF Viewer' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.

Reproduced on the latest versions of Firefox Nightly 88.0a1 (2021-03-19), beta 87.0 and release 86.0.1 on Ubuntu 20.04.
Setting up flags and a component in order to get the dev team involved.
If you feel it's an incorrect one please feel free to change it to a more appropriate one.
Assigning it a severity of S4.
Not a recent regression since it can be reproduced back to Firefox 71.0.
