bug(platform): list items are not updating

[N1XUS]

Is this a bug, enhancement, or feature request?

bug

Briefly describe your proposal.

Platfrom list items are not updated after initial value has been set. The issue is that items are being populated only on ngOnInit event.
Additionally, stackblitz examples for platform list are not working

Which versions of Angular and Fundamental Library for Angular are affected? (If this is a feature request, use current version.)

current

If this is a bug, please provide steps for reproducing it.

Use this data provider:

export class ListDataProvider extends DataProvider<Address> {
    i = 0;
    items = new BehaviorSubject<Address[]>([]);
    constructor() {
        super();
    }
    fetch(params: Map<string, string>): Observable<Address[]> {
        let data = LIST_ELEMENTS;
        const name = params.get('name');
        if (name) {
            const keyword = name.toLowerCase();
            data = data.filter((city) => city.name.toLowerCase().indexOf(keyword) > -1);
        }
        setTimeout(() => {
            this.items.next(data);
        }, 500);
        return this.items.asObservable();
    }
}

Please provide relevant source code if applicable.

Is there anything else we should know?
