Previously, mdBook used JavaScript to add header links, so we skipped checking the book. As of https://github.com/rust-lang/rust/pull/39966, it no longer does, so we can start checking again. There is a twist, though: it uses name instead of id, so let's test for both. They're both valid links anyway, so it's good to have the checker check anyway. |
