Hi! I have a very unpleasant bug with reexporting default submodule export in index files. It is a very common case for me and it works with current bundler (Webpack), but looks broken in the editor.

Steps to Reproduce:

1. Create submodule.js file with following content:

export default function DefaultExport () {}
export function TestExport () {}

2. Create index.js with reexports:

export default from './submodule1.js';
export TestExport from './submodule1.js';

VS Code highlights reexports as syntax errors and breaks "Go To Definition" logic, which is very useful.

Here is my jsconfig.json file:

{
    "compilerOptions": {
        "target": "ES6",
        "jsx": "react"
    },
    "exclude": [
        "node_modules",
        "build",
        "tools",
        ".idea"
    ]
}

Thanks!
