Steps to reproduce

const app = getCurrentInstance()
setTimeout(() => {
  app.appContext.app.runWithContext(() => {
    alert(getCurrentInstance() === app);
  });
}, 1000);

The above code always alerts false, ideally it should output true.

What is expected?

const app = getCurrentInstance()
setTimeout(() => {
  app.appContext.app.runWithContext(() => {
    alert(getCurrentInstance() === app);
  });
}, 1000);

The above code always alerts false, ideally it should output true.

What is actually happening?

getCurrentInstance should be running in an app context, like inject

runWithContext provides context to the function，In my scene, I cannot automatically pass context

openDatasetSelect internally uses the render method to render the component into the body, and the component internally uses getCurrentInstance

Any additional comments?

The getCurrentInstance is not recommended for use. The fundamental issue is how to obtain the runWithContext again within the asynchronous function inside the runWithContext function?

The minimal reproduction does not make sense to me.
Please provide a reproduction that closely matches your actual application.
