VSCode Find All References Not Working for Imported Functions

Type: Bug

Description

I am encountering an issue with the 'Find All References' feature in VSCode after updating to the latest version. When I export functions from a module and import them using import * as user from './user', the 'Find All References' feature does not find any references to the functions within the imported module.

Steps to Reproduce

Create a file named user.ts with the following content:

export function method1() {
    console.log('method1');
}

export function method2() {
    console.log('method2');
}

Create a file named api.ts with the following content:

import * as user from './user';

export const api = {
    user
};

Create a file named index.ts with the following content:

import { api } from './api';

api.user.method1();
api.user.method2();

Expected Behavior

The 'Find All References' feature should find all references to method1 and method2 in the user module when invoked on any of these functions.

Actual Behavior

The 'Find All References' feature does not find any references to method1 and method2 in the user module.

Workaround

The issue can be temporarily resolved by exporting an object containing the functions instead of exporting the functions directly. For example, in user.ts, export an object like export const user = { method1, method2 } and then import this object in api.ts and index.ts.
