I'm leaning towards the something in the dataset_description.json not playing well with the markdown to jsx library: https://github.com/quantizor/markdown-to-jsx/issues/496 https://github.com/quantizor/markdown-to-jsx/issues/473

Re that second link, ds004504 README has a lot of consecutive spaces in it.

Opened #3000 to do the minimal fix. Not sure if it would be better to switch to another library that doesn't implement a CFL with regular expressions.

I implemented the switch to react-markdown in #3009. This is closer to the GitHub markdown feature set anyways that we are aiming for.
