This is safe to land because the only changes are CSS fixes and dependency updates.

This is important to land because some of those CSS bugs are really annoying. 😉

Ah interesting. I don't think that a MIT/BSD-3-Clause license is actually a problem, but that dependency isn't necessary for our english-only use of MDBook. I was already doing the work to make it optional, so I'll get to it. Probably need another version of MDBook published.

@mattico there's a new patch release of mdbook, should this be re-opened?
