DevExtreme started to create unnecessary elements in TreeView

Question

After updating to DevExtreme 23.2 I confronted problem showe on screenshot

And this is what's expected to be seen

For some reason after updating to new version it creates blank expand element though the icons must be the root elements of the TreeView

This is the code that is used

<div class="menu-container">
  <dx-tree-view [items]="items"
                [keyExpr]="'key'"
                [selectionMode]="'single'"
                [focusStateEnabled]="false"
                [expandEvent]="'click'"
                [animationEnabled]="false"
                [height]="'100%'"
                [width]="'100%'"
                itemTemplate="itemTemplate"
                (onItemSelectionChanged)="onItemSelectionChanged()"
                (onItemExpanded)="onItemExpanded($event)"
                (onItemClick)="onItemClick($event)">
    <div *dxTemplate="let menuItem of 'itemTemplate'"
         [ngClass]="{
          'is-parent': menuItem.items && menuItem.items.length > 0
         }">
      <a (click)="onMenuItemClick($event)"
         [attr.href]="menuItem.route ? menuItem.route : null">
        <i *ngIf="menuItem.icon"
           class="dx-icon mdi mdi-{{menuItem.icon}}">
        </i>
        <span>{{menuItem.name}}</span>
      </a>
    </div>
    </dx-tree-view>
</div>
