Angular Highcharts dynamic import produces no additional chunk


Im trying to lazy load Highcharts library with dynamic import in Angular CLI project. In another cases, it’s working perfectly fine and creates separate chunk. But in this scenario, while library is still included in main chunk. No additional chunk is created. Any idea what’s wrong?

Basic code example (working, but no additional js chunk):

import(/* webpackChunkName: "highcharts" */ 'highcharts/').then(
    (module) => {

tc config

    "compilerOptions": {
        "baseUrl": "./",
        "outDir": "./dist/out-tsc",

I found the issue here: So to dynamic import we need to use custom build library without hardcoded imports inside (solution here).
