Bug

What is the current behavior? @hot-loader/react-dom is installed following instructions:

yarn add react-dom@npm:@hot-loader/react-dom

yarn outdated shows react-dom as exotic

❯ yarn outdated
yarn outdated v1.13.0
info Color legend :
 "<red>"    : Major Update backward-incompatible updates
 "<yellow>" : Minor Update backward-compatible features
 "<green>"  : Patch Update backward-compatible bug fixes
Package   Current Wanted Latest Package Type URL
react-dom 16.8.2  exotic exotic dependencies npm:@hot-loader/react-dom
✨  Done in 2.46s.

package.json before yarn upgrade:

{
  "dependencies": {
    "@hot-loader/react-dom": "^16.8.2",
    "react-dom": "npm:@hot-loader/react-dom",
  }
}

package.json after yarn upgrade:

{
  "dependencies": {
    "@hot-loader/react-dom": "npm:@hot-loader/react-dom",
    "react-dom": "npm:@hot-loader/react-dom",
  }
}

If the current behavior is a bug, please provide the steps to reproduce.

See above

What is the expected behavior? The package.json should not erase the alias

Please mention your node.js, yarn and operating system version.

I'm not sure but it just seems package aliases are behaving... strangely. Not sure if connected to workspaces, or to scoped packages.

I could reproduce it a few days ago with babel-preset-env@npm:@babel/preset-env, but I'm not affected anymore (for now) as I no longer need the hack.
