rustdoc: intradoc links to std don't behave as expected #85106
Description
Currently, rustdoc links to types in std that come from core or alloc resolve to the latter two crates. (They also link to nightly docs even on stable versions, but that's orthogonal.) This behavior is debatably appropriate for crates using std, but it's not a big deal.
However, explicit intradoc links (e.g. [std::vec::Vec]) also exhibit this behavior, which as a documentation writer I find confusing: if a path resolves to a different crate than the one I specified, I'm surprised.
