Demo host app of workbench application platform fails to start

[danielwiehl]

Current behavior

Since Angular 8 the demo host app of 'workbench application platform' fails to start with the following error:

• polyfills-es2015.0c97deb922efbec0d091.js:1 Uncaught TypeError: Cannot set property 'true' of undefined
• Uncaught Error: In this configuration Angular requires Zone.js

The error does not happen when serving the app with ng serve command line tool.

The app requires the 'web-animations-js' polyfill because the workbench uses AnimationBuilder API.

This issue is related to angular/angular-cli#14518.

Expected behavior

The host app can be started even with 'web-animations-js' polyfill imported.

Minimal reproduction of the problem with instructions

1. Build the app with npm run app:workbench-application-platform:build-now:host-app
2. Change to the directory of the generated app
3. Install http-server from npm with npm i http server -g
4. Start the http-server in the terminal with http-server command
5. Open your browser and enter following address: http://localhost:8080/index.html
6. See that no content is displayed and the error in the browser console.

Environment

• SCION Workbench version: 0.0.0-beta.23
• Angular version: 8.0
