Current behavior
Even after setting theme dropdown component not changes its skin.

Expected behavior
to work consistent :)

Minimal reproduction of the problem with instructions (if applicable)

        <tag-input [ngModel]='post.tags' displayBy='name' (onAdd)='onTagAdd($event)'
                   [theme]="isDark ? 'dark' : ''"
                   (onRemove)='onTagRemove($event)'
                   [allowDupes]="true"
                   [ngModelOptions]='{standalone: true}'>
          <tag-input-dropdown [autocompleteObservable]='requestAutocompleteItems' displayBy='name'></tag-input-dropdown>
