cargo add to package within a virtual workspace behaves differently when translating package name

[dohse]

Problem

cargo add behaves differently when operating on a package in a virtual workspace depending whether the package name is not translated or translated (cargo shows warning: translating …).

In the first case cargo adds a reference to dependency declared in [workspace.dependencies] - which I believe is the desired result.

In the later case cargo adds the dependency and the version, but does not reference [workspace.dependencies] - I believe this is not desired.

Steps

Reproduction script when adding parking-lot:

> mkdir workspace
> cd workspace
> cat > Cargo.toml
[workspace]
resolver = "2"

[workspace.dependencies]
parking_lot = "0.12.1"
> cargo new x
     Created binary (application) `x` package
> cargo add -p x parking-lot
    Updating crates.io index
warning: translating `parking-lot` to `parking_lot`
      Adding parking_lot v0.12.1 to dependencies.
