Bug description

Because of complex reasons it is impossible to execute cargo test in a project that links to pyo3 (specifically with the extension-module feature). As a workaround I put a [workspace] in my Cargo.toml and have a separate tests package to test my rust code. To run the tests I do cargo test --package tests, which works fine (for now I have only an example test, because I ran into this issue).

Unfortunately when clicking the 'Run test' button on the tests/tests.rs file (which is part of the tests package member of the workspace) in VSCode, rust-analyzer passes --package icicle-python (the root package).

Reproduce the issue using the icicle-python repository at commit 21531db2e0f87a729ccae5738afc4bbff1be029a, with the workspace's tests/tests.rs and its Cargo.toml setup. Start by comparing cargo test --package tests with the command issued by VSCode's Run test action; done means the action selects the tests workspace package instead of icicle-python.
