Printing looks different after cleanup

[CodingFabian]

can be at least reproduced with several PDFs on FF 32a on my Mac .

Load the PDF, print (to pdf) - the PDF will look good quite identical.

Reload
Load the same PDF, wait 45 seconds, print (to pdf) - the PDF will look different. In most cases fonts which were bold are no longer bold.

I can reproduce this using Windows 7 x64, Firefox Nightly 33.0a1 (64-bit, HWA on) and the latest PDF.js development version.

this might even be a firefox bug. what i can see is that the canvas.context font is set correctly, but the requested font is not used when setting the text.

just to add: cleanup is not the root cause. If we would not render any page to the screen, the font would be broken as well.
If cleanup would not happen the font would work because it comes from the cache.

Evidence: built-in Firefox viewer (looks like modified) has no this problem.
Tested on Firefox 46.0.1 (with built-in viewer 1.3.231)

Closing as (most likely) fixed by #7694.
