`rustdoc --show-coverage` misses associated items on public items re-exported from private modules

I tried this code:

// src/lib.rs
//! ```
//! ```

pub mod foo;
pub mod bar;

// src/foo.rs
//! ```
//! ```

/// ```
/// ```
pub struct Foo;

impl Foo {
    /// ```
    /// ```
    pub fn foo() {}
}

// src/bar.rs
//! ```
//! ```

mod inner {
    /// ```
    /// ```
    pub struct Bar;

    impl Bar {
        pub fn bar() {}
    }
}

pub use inner::Bar;

> cargo rustdoc -- --show-coverage -Zunstable-options

I expected to see this happen:

+-------------------------------------+------------+------------+------------+------------+

+-------------------------------------+------------+------------+------------+------------+

Instead, this happened:

+-------------------------------------+------------+------------+------------+------------+
| File                                | Documented | Percentage |   Examples | Percentage |

| src/foo.rs                          |          3 |     100.0% |          3 |     100.0% |
| src/lib.rs                          |          1 |     100.0% |          1 |     100.0% |
+-------------------------------------+------------+------------+------------+------------+

+-------------------------------------+------------+------------+------------+------------+

src/bar.rs is ignoring the undocumented public method.

The same also happens with non-inline modules.

Reproduce the issue from the src/lib.rs, src/foo.rs, and src/bar.rs examples with cargo rustdoc -- --show-coverage -Zunstable-options. Compare coverage for the re-exported Bar and its undocumented associated method, including the non-inline module case. Done means the report counts the associated item and reflects its missing documentation.
