[Bug] CRA incompatibility on HTTPS=true flag

Describe the bug

HTTPS=true spits this error: EROFS: read-only filesystem, open '/node_modules/webpack-dev-server/ssl/server.pem' after migrating to yarn 2.

To Reproduce

From a fresh CRA install, prepend HTTPS=true flag in the scripts.start from your package.json.

It should now look like this

scripts: {
  start: "HTTPS=true react-scripts start"
}

To clarify, yarn starts perfectly without HTTPS=true, I’m suspecting webpack-dev-server creates a self-signed certificate and writes it into its own directory, except they’re all now read-only.

Environment if relevant (please complete the following information):

• OS: OSX
• Node version v10.16.3
• Yarn version 2.0.0-rc.27

This has been solved by adding a meta dependency on package.json:

"dependenciesMeta": {
    "webpack-dev-server": {
      "unplugged": true
    }
}

From: https://next.yarnpkg.com/configuration/manifest/#dependenciesMeta.unplugged

This still produces the same error for us, yarn=2.0.0-rc.29
