Many thanks to the Seed team for all your work. This issue was described in https://github.com/rust-lang/docs.rs/issues/1200 and fixed by https://github.com/rust-lang/rust/pull/79936, but docs.rs did not automatically rebuild docs for affected crates after the fix. I believe a rebuild should be all that is necessary to fix this (either as a patch or with next release).
