Dynamic shared runtime exposed with Store lost shared data

[ytytsophia]

App1 and App2 are in different git repository App1 expose app1/getProjectId like :

class Store<T> {
  _value: T;

  set value(value: T) {
    this._value = value;
  }

  get value() {
    return this._value;
  }
}
const projectIdStore = new Store<string | undefined>();

const getProjectId = () => projectIdStore.value;

export const setProjectId = (value: string | undefined) =>
  (projectIdStore.value = value);
export default getProjectId;

I call setProjectId('1') in App1, and make app1/getProjectId shared in init functions like

shared: {
        react: {
          version: '17.0.2',
          scope: 'default',
          lib: () => React,
          shareConfig: {
            singleton: true,
            requiredVersion: '^17.0.2',
          },
        },
        'react-dom': {
          version: '17.0.2',
          scope: 'default',
          lib: () => ReactDOM,
          shareConfig: {
            singleton: true,
            requiredVersion: '^17.0.2',
          },
        },
        'project/getProjectId': {
          shareConfig: {
            singleton: true,
            requiredVersion: '^1.0.0',
          },
        },
      },

which I expect is in App2 , when I call app1/getProjectId, I can get the value which I set in App1 before, but I got undefined What should I suppose to do ? Thanks
