Intra-doc links not resolved in workspace with proc-macro

Problem

There are doc links that sometimes refuse to work, I found a reproducible way of witnessing it.

Steps

Make sure rust-analyzer is not running for reproducibility. clone doc-bug, run cargo clean and cargo doc --open at the root of the workspace. Click on the awint_macros crate in the "Crates" list and scroll all the way to the bottom of the lib docs (I can't reduce further because it causes the problem to go away). There is a broken doc link with the literal text [awint_macro_internals::awint_macro_inlawi] towards the bottom.

Then, go to the source code awint/awint_macros/src/lib.rs and make some dummy change like adding a "// hello" comment somewhere. Run just cargo doc and refresh, now the doc link is no longer broken.

Possible Solution(s)

No response

Notes

It probably has to do with cargo-doc getting confused when there are multiple transitive dependencies and multiple reexports of items. Recompiling sometimes breaks or fixes it strangely.

Reproduce the failure with the linked doc-bug workspace by running cargo clean and cargo doc --open, then compare the generated awint_macros documentation before and after the dummy change in awint/awint_macros/src/lib.rs. Start by tracing how cargo doc resolves intra-doc links across transitive dependencies and reexports. Done means the awint_macro_internals link resolves consistently after a clean documentation build.
