How to refer in JsDoc (VS Code / IntelliSense) to class from another file without direct import?

Problem

I use Visual Studio Code and use IntelliSense with JsDoc comments. I have two modules with class declarations:

/**
 * This is Foo class 
 */
export default class Foo {
    constructor() {}
}

and

/**
 * This is Bar class 
 */
export default class Bar {
    constructor() {}

    /**
     * Init Bar from Foo
     * @param {Foo} foo instance of Foo
     * @returns {Bar}
     */
    static initFromFoo(foo) {
        return new Bar();
    }
}

Class Bar use Foo as param for the method initFromFoo but IntelliSense doesn't understand that @param Foo is referred to class Foo and don't work properly and says that foo:any,

How can I make IntelliSense work well?

What I have tried

1. Import ./foo into ./bar- this makes IntelliSense work well but I don't need this import I need just reference to the type definition.
2. Add reference to another file like in TypeScript /// <reference path="./foo"> - no effects
3. Create jsconfig.json file with the next content:

{
    "compilerOptions": {
        "target": "es6",
        "allowSyntheticDefaultImports": true,
        "checkJs": true
    },
    "exclude": [
        "node_modules"
    ]
}

no effects too. It just highlights error Cannot find name 'Foo'.ts(2304)

P.S. It looks like IntelliSense limitation that related to ES6 modules. Because if I remove export/import from both files IntelliSense work as expected

P.S.S. Sorry for links to images my repo is too low for image posting.

It is possible to import type by import(path) statement. For example:

/**
 * Init Bar from Foo
 * @param {import('./foo').default} foo instance of Foo
 * @returns {Bar}
 */
static initFromFoo(foo) {
    return new Bar();
}

OR

/**
 * @typedef {import('./foo').default} Foo
 *
 * Init Bar from Foo
 * @param {Foo} foo instance of Foo
 * @returns {Bar}
 */
static initFromFoo(foo) {
    return new Bar();
}

P.S. It is hack only for Visual Studio Code. It isn't valid JsDoc.
