@preact/signals-react crashes on production build, at least using `react-scripts build`

See original GitHub issue

cf: https://github.com/preactjs/signals/issues/86

The error here is: TypeError: Invalid value used as weak map key

What appears to be the case is that internals.ReactCurrentOwner.current is not set.

Here are the versions I have installed:

    "@preact/signals-react": "^1.0.0",
    "react": "^18.2.0",
    "react-dom": "^18.2.0",
    "react-scripts": "5.0.1",
    "typescript": "^4.4.2",

and the browser configuration:

  "browserslist": {
    "production": [
      ">0.2%",
      "not dead",
      "not op_mini all"
    ],
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  }

How to reproduce:

using create-react-app (typescript template), create a react app
use @preact/signals-react
yarn build (creates a production build)
open your built browser-app in the browser
behold this error
