When opened in StackBlitz, [this documentation sample](https://www.infragistics.com/products/ignite-ui-angular/angular/components/dock-manager#angular-dock-manager-example) renders the DM like this:  It appears that the `defineCustomElements` method is not invoked anywhere in the sample. If added, the sample renders correctly - check [this fork](https://stackblitz.com/edit/angular-with-dock-manager-defined?file=src%2Fapp%2Fdock-manager-sample%2Fdock-manager.component.html).
