signals/react: 'default' is not exported by react/jsx-runtime

When trying to generate a production build in a Vite react app, we get the following error:

'default' is not exported by react/jsx-runtime, imported by node_modules/@preact/signals-react/dist/signals.module.js

It appears this error originates from these lines https://github.com/preactjs/signals/blob/main/packages/react/src/index.ts#L9-L10, where it’s using default imports for the two runtimes, while the jsx-runtime package appears to only provide named exports?

Update on this, it looks like there is an issue with how @preact/signals-react incorporates with the JSX runtime. You can circumvent this by updating vite react plugin to use the classic jsxRuntime, though I’m unsure what the tradeoffs are there, e.g.:

export default defineConfig({
  plugins: [
    react({
      jsxRuntime: "classic",
    }),
  ],
});

Running into the same issue while building a Vite TypeScript React application.

Edit: @cafreeman - I changed the version to 1.1.1 on my package.json and it has fixed the issue with the build. Although, probably need to take a deeper look to fix in future.
