Can confirm. It's this line right here: https://github.com/ziglang/www.ziglang.org/blob/72cbd7c2d19f5f0b2b5cbfdeb9f288b5b2df9392/src/documentation/0.13.0/index.html#L319

where I guess it's supposed to be using something like this here: https://github.com/ziglang/www.ziglang.org/blob/72cbd7c2d19f5f0b2b5cbfdeb9f288b5b2df9392/src/documentation/0.12.0/index.html#L306C19-L306C25
