git dependencies not updating in analyzer after updating repository and doing "cargo update"

I have a project that I'm working on that has a private repository that I'm using as a git dependency. Everything works fine until I update the private repository. I push a new version of the code to the private repository then cargo update [dependency] to download the new version to the project that depends on it, and confirm in my Cargo.lock that the new version is there.

The change I'm making in this scenario fixes an error that was showing up from rust-analyzer, and after doing the above steps the error is still there. cargo build works fine and shows no error but still doesn't update rust-analyzer. It's like rust-analyzer is using a cached version of the code that I can't locate.

Start by reproducing the report with a Rust project that uses a private git dependency: update the dependency repository, run cargo update, and compare Cargo.lock with rust-analyzer's diagnostics. Investigate how rust-analyzer refreshes git dependency sources and determine what refresh or cache invalidation makes the analyzer use the updated code; done means diagnostics reflect the new dependency while cargo build continues to succeed.
