Prevent drag event to start when input field was clicked in Angular 7

I'm using the package ngx-sortable for Angular 7. (https://github.com/manishjanky/ngx-sortable).

The sort mechanism with drag and drop works well. But the problem appears, if there are input fields inside the sortable container. I can't highlight text inside the input because the dragging event starts immediately.

The code in general is the following:

<ngx-sortable [items]="items" [name]="'List'" (listSorted)="listOrderChanged($event)">
    <ng-template let-item>
        <div class="sortable-list-item">
            {{item}}
            <input type="text" value="example" />
        </div>
    </ng-template>
</ngx-sortable>

Is there a way to prevent ngx-sortable to start the drag operation without changing the package?
