Empty comments in Angular application

Is there any configuration setting which would remove these empty comments and whitespace?

My build command is ng build --environment prod --progress false --target production and tsconfig is:

{
    "compileOnSave": false,
    "compilerOptions": {
        "alwaysStrict": true,
        "baseUrl": "/",
        "emitDecoratorMetadata": true,
        "experimentalDecorators": true,
        "forceConsistentCasingInFileNames": true,
        "lib": [ "es2015", "dom" ],
        "module": "es2015",
        "moduleResolution": "node",
        "newLine": "CRLF",
        "noFallthroughCasesInSwitch": true,
        "noImplicitAny": true,
        "noImplicitReturns": true,
        "noUnusedLocals": true,
        "noUnusedParameters": false,
        "outDir": "./dist/out-tsc",
        "removeComments": true,
        "skipDefaultLibCheck": true,
        "skipLibCheck": true,
        "strictNullChecks": true,
        "target": "es5",
        "typeRoots": [ "./node_modules/@types" ]
    }
}

@angular/cli: 1.0.4
node: 7.2.1
os: win32 x64
@angular/common: 4.1.3

Thank you.
