Ah. Badly-implemented isomorphic rendering, with client-side routing that works, but a server-side implementation that’s partially broken.

I disable JavaScript in general for a significantly better experience of the web, and didn’t suspect anything like this since everything else was working perfectly.

Incidentally, I strongly oppose the use of client-side rendering for pages like this (not CSR in all cases, but yes for a site like this). Barring the small matter of this one broken page, the result is fairly uniformly inferior to the no-JavaScript version: it has a heavier footprint, doesn’t work as well (some history interactions are a touch dodgy, no loading throbber, can’t interrupt navigation with Escape, &c.), and feels slower than fresh page loads anyway. It’s foolish, harmful complexity.
