Angular drag and drop using transferArrayItem points to wrong index number upon filtering (working example)

Question

I am trying to filter a list of items using the Drag Material CDK... all is working well when my list is not filtered, however when I filter it, and drag and drop, I get the wrong item (wrong index) on the drop, I created a working example, as you can see, filter by let's say "av" and drag avocado to drop area and you will get Carrot as the index is referring to the old data source, any ideas are appreciated,

here is a working example of the problem: https://stackblitz.com/edit/angular-agf3kv-wjxwdm?file=app/cdk-drag-drop-disabled-sorting-example.css

You should use itemsFiltered as cdkDopListData.

<div
  cdkDropList
  [cdkDropListData]="itemsFiltered" <-- HERE
  class="example-list"
  cdkDropListSortingDisabled
  (cdkDropListDropped)="drop($event)">
  <div class="example-box" *ngFor="let item of itemsFiltered" cdkDrag>{{item}}</div>
</div>
