I’m trying to create library, built by webpack. Creating an entry with some exported function works just fine. The problem starts when I add splitChunks property with any of these settings: chunks: "all", "async" or "initial". When I’m trying to use the exported module I got undefined.

Bug report

What is the current behavior? Using splitChunks and library makes exports undefined.

If the current behavior is a bug, please provide the steps to reproduce.

{
    entry: "bundle.ts",
    output: {
        library: "MyLibrary",
        libraryTarget: "window"
    },
    optimization: {
        splitChunks: {
            chunks: "all"
        }
    }
}

What is the expected behavior? Exported modules should be available in window.MyLibrary. I repeat, my current configuration, without splitChunks is fine and I can use my exported function.
