if we have a textarea next to a dropdown and pass [autoresize]=true to it, the virtual scroll doesn't work correctly.
Code to reproduce:

<div class="card flex justify-content-center">
  <textarea pInputTextarea rows="1" [autoResize]="true"></textarea>
  <p-dropdown
    [options]="items"
    [(ngModel)]="selectedItem"
    placeholder="Select Item"
    [virtualScroll]="true"
    [virtualScrollItemSize]="38"
  ></p-dropdown>
</div>

constructor() {
    this.items = [];
    for (let i = 0; i < 50; i++) {
      this.items.push({ label: 'Item ' + i, value: 'Item ' + i });
    }
  }

Hi,

The issue is opened in the wrong repo, could you please open it on PrimeNG and tag me? I can't add it into the PrimeNG milestone from here nor I can fix it.
