MultiSelect: pTemplate selectedItems does not work

[delrem32]

Describe the bug

When pTemplate="selectedItems" is defined, the multiselect ignores it.

<p-multiselect
  [options]="countries"
  [(ngModel)]="selectedCountries"
  optionLabel="name"
  placeholder="Select Countries"
  display="chip"
  appendTo="body"
>
  <ng-template let-selectedCountries pTemplate="selectedItems"> //<--Always ignored
    <div *ngFor="let country of selectedCountries">
      {{ 'TEST' + country.name }}
    </div>
  </ng-template>
  <ng-template let-country pTemplate="item">
    <div>
      <div>{{ 'TEST INNER ITEM ' + country.name }}</div>
    </div>
  </ng-template>
</p-multiselect>
