Mat-Select 仅在单击底线时打开

Question

I implemented Mat-Select from Angular material (TS) and noticed interesting behavior. Dropdown not opening until clicked on bottom line of mat-select and I know when I worked before with Mat-select field it was opening when I clicked anywhere on field. What is the problem?

  <mat-form-field>
    <mat-label>Toppings</mat-label>
    <mat-select [formControl]="toppings" multiple>
      <mat-option *ngFor="let topping of toppingList" [value]="topping">{{
        topping
      }}</mat-option>
    </mat-select>
  </mat-form-field>

might be a cache issues or the dynamic data must be loading late (adding a condition might help)
