What Arxiv URLs were you trying?

LaTeX is really tricky to parse, which is why you're seeing those "failed to render" errors. Judging from our logs, it works about ~80% of the time. That's up a lot from plain Pandoc though - it could render hardly anything from Arxiv.

I tried some more and still got the "are you sure this is a valid URL?" e.g., https://arxiv.org/abs/gr-qc/0702106

Tried https://arxiv.org/abs/1511.06343 and a couple others and got the "failed to render."

Tried cloning engrafo, then installing docker, then building engrafo, then my disk was filling up and decided I'm done with this for now.
