window.__FEDERATION__.__SHARE__ has incorrect loaded value for some shared dependency

[romain-trotard]

Describe the bug

Hello :)

Module federation tracks shared dependencies with the global object window.__FEDERATION__.__SHARE__. There can be issues with the loaded property, which tracks which dependency is loaded.

It happens for the react dependency with the following configuration:

      shared: {
        react: {
          singleton: true,
          eager: true,
          requiredVersion: '^18.3.1',
        },
        'react-dom': {
          singleton: true,
          eager: true,
          requiredVersion: '^18.3.1',
        },
      },

At runtime we can see that react is not marked as loaded:

BUT

If I remove react-dom from the shared dependencies, it works:

---

Expected vs actual behavior

react should be marked as loaded: true even when having react-dom as a shared dependency.

---

When it works

The configuration works when:

• I have only react as a shared dependency

• I have react and lodash as a shared dependencies

• I have react and react-is as shared dependencies

• Run: pnpm -w run nx run react_ts_remote:serve:webpack
• Go to: http://127.0.0.1:3005/
• In the devtool log: window.__FEDERATION__.__SHARE__['react_ts_remote:0.0.0'].default
• You can see that react is not marked as loaded
