Description

Reproduction Steps

Create a workspace with two libraries:

foo/src/lib.rs:

pub struct Foo;

bar/src/lib.rs:

/// Documentation here
pub use foo::Foo;

pub use foo::*;

Archive containing the exact configuration I tested: glob-doc-missing.zip

Expected Outcome

"Documentation here" should appear on the documentation page of bar::Foo.

Actual Output

"Documentation here" appears in the item list of bar but not on the documentation page of bar::Foo.

Research direction

Start by reproducing the issue with foo/src/lib.rs and bar/src/lib.rs using rustdoc, then compare bar's item list with the documentation page for bar::Foo. The work is complete when "Documentation here" appears on bar::Foo's documentation page as well as in bar's item list.
