Can't use this within a project with `wasm-bindgen` due to cyclic dependency

- `import_map` enables `serde_json/preserve_order`
- `serde_json/preserve_order` depends on `indexmap` (https://docs.rs/crate/serde_json/latest/features)
- `indexmap` depends on `hashbrown`
- `hashbrown` depends on `ahash` by default.
- `ahash` depends on `const-random`

and the result is

```
❯ cargo check
Updating crates.io index

```

Start by reproducing the dependency graph with `cargo check` in a project using `wasm-bindgen` and `import_map`, then inspect the listed `serde_json`, `indexmap`, `hashbrown`, `ahash`, and `const-random` dependencies. Done means the cyclic package dependency is resolved and the affected project checks successfully.
