Is pdf.js neglecting font problems? I've read some font-related questions from other people before, and there is no answer.

No, we're not. If you check https://github.com/mozilla/pdf.js/pulls?q=label%3A4-font-conversion+is%3Aclosed+is%3Apr amongst others, you'll see that many have been solved before. Note that these issues are usually far from trivial to solve and may therefore take a long time, also because there are not many people that can debug such issues. Please refrain from posting such comments as they're not helpful for solving the problem.

Trying the file with Firefox 62.0b9 and the issue is still there. We experience the similar problem with many documents displayed with the corrupted fonts.
