Description
rust-analyzer version: rust-analyzer version: 0.4.2145-standalone (d7628c0a8 2024-10-12) [/Users/sytten/.vscode/extensions/rust-lang.rust-analyzer-0.4.2145-darwin-arm64/server/rust-analyzer]
rustc version: rustc 1.81.0 (eeb90cda1 2024-09-04)

If you have the structure
src
│ lib.rs
│
├── tests
│ ├── mod.rs
│ └── a.rs
in lib.rs you have
#[cfg(test)]
mod tests
in mod.rs you have
mod a;
Then the test cases in a.rs are marked as unlisted: This file is not included anywhere in the module tree, so rust-analyzer can't offer IDE services

Research direction
Reproduce the minimal module tree using lib.rs, tests/mod.rs, and tests/a.rs, with tests declared under #[cfg(test)]. Then trace rust-analyzer's handling of these module declarations and verify that a.rs is included in the module tree rather than marked unlisted, with IDE services available there.
