CLI esm:add seems to not respect aliases in transitive dependencies

[effulgentsia]

deno run -A -r https://esm.sh init
deno task esm:add react:preact/compat @radix-ui/react-slot

results in a deno.json file containing:

  "imports": {
    "@radix-ui/react-slot": "https://esm.sh/v135/*@radix-ui/[email protected]",
    "react": "https://esm.sh/v135/[email protected]/compat"
  },
  "scopes": {
    "https://esm.sh/v135/": {
      "@radix-ui/react-compose-refs": "https://esm.sh/v135/@radix-ui/[email protected]"
    }
  }

The * in the first line is nice: it means when @radix-ui/react-slot imports from react that specifier is left external and the import map is able to get that from https://esm.sh/v135/[email protected]/compat.

However, the last line does not have a *, which means when @radix-ui/react-compose-refs is imported by @radix-ui/react-slot and it imports from react, esm.sh doesn't make it external and therefore fetches React for it rather than Preact/compat.
