Hmm, I'm pretty sure that failure is due to #135560 instead.

resolve: Support imports of associated types and glob imports from traits Follow up to rust-lang#134754, part of rust-lang#134691. This PR also closesrust-lang#138711 now. Prohibiting `use Trait::AssocType;` at name resolution stage doesn't make sense, the name itself is perfectly resolveable. It's a type checker's problem that the necessary generic args are not passed when the imported `AssocType` is used, so an error should be reported there. And since we can import associated trait items now, glob imports from traits can also be allowed.
