I tried this code: ```rust #![doc(xxx)] ``` I expected to see this happen: Rustdoc warns that `xxx` is an unknown doc attribute. Instead, this happened: Rustdoc silently ignores the attribute. ### Meta `rustdoc --version`: rustdoc 1.52.0-nightly (0148b971c 2021-02-18) Found while working on https://github.com/rust-lang/rust/pull/82651.
