recursively reexported crates are erroniously deduplicated.

Code

-- Cargo.toml --
[package]
name = "test-re"
version = "0.1.0"
edition = "2024"

[dependencies]
middle.path = "middle"

[workspace]
members = ["inner", "middle"]

-- inner/src/lib.rs --
//! Innermost crate.

-- inner/Cargo.toml --
[package]
name = "inner"
version = "0.1.0"
edition = "2024"

[dependencies]

-- middle/src/lib.rs --

pub use inner;
pub use inner as inner_renamed;

-- middle/Cargo.toml --
[package]
name = "middle"
version = "0.1.0"
edition = "2024"

[dependencies]
inner.path = "../inner"
-- src/lib.rs --
pub use middle::*;

pub use inner_renamed as renamed_again;

Reproduction Steps

cargo doc --open --no-deps

Expected Outcome

test-re docs have 3 items shown at crate root, inner, inner_renamed, and renamed_again.

Actual Output

only inner and renamed_again are present

Version

rustdoc 1.100.0-nightly (2e2b193f8 2026-09-02)

Additional Details

found while building a minimal reproducer for #162161

Start with the minimal workspace in the issue and run cargo doc --open --no-deps to reproduce the missing inner_renamed item. Trace rustdoc's handling of recursively reexported crates and deduplication. Done means the test-re crate root shows inner, inner_renamed, and renamed_again.
