Unable to run a specific doctest

I need to run a particular doc test.

To run the docket I use the following command

cargo test --all-features --doc 'package::core::Package\ (line\ 58)'

I expected to see this happen: Only the particular doctest package::core::Package at line 58 is executed.

Instead, this happened: the doc test runs, however 2 different other doc tests also run.

➜  bpx-rs git:(develop) ✗ cargo test --all-features --doc 'package::core::Package\ (line\ 58)'          
    Finished `test` profile [unoptimized + debuginfo] target(s) in 0.06s

The same issue occurs on both nightly and stable.

cargo +nightly --version

cargo 1.100.0-nightly (e8cb624d5 2026-08-22)

cargo --version

cargo 1.93.0 (083ac5135 2025-12-15)

rustc --version --verbose:

Start by running the reported cargo test --all-features --doc command against the bpx-rs example and compare its filter behavior on stable and nightly. Investigate how Cargo or rustdoc matches the doctest name and line number; done means the command executes only package::core::Package at line 58 while preserving expected doctest filtering.
