This regressed in 465ac26 / #103928, cc @chenyukang

Rustdoc is special because it's more forgiving with errors than rustc. I'm curious to understand where we're suppressing an error in rustdoc due to _ infer types being present outside of an typeck body, and whether it should just be reporting an error...
