Description

RA server suggest imports from [dev-dependencies] in non-test scopes. It also shadows alternative import paths of the same type via a different import path.

The sample code has instructions in crates/a/src/lib.rs.

Doesn't seem to work 🤷 ``

Research direction

Start with the reproduction instructions in crates/a/src/lib.rs and the linked MVE. Reproduce the suggested imports in a non-test scope, then trace why a dev-dependency is selected and why an alternative re-export path is shadowed. Done when both incorrect suggestions are resolved and the reproduction behaves correctly.
