I have a table with tooltips inside rows:

 <ng-container matColumnDef="icons">
    <th mat-header-cell *matHeaderCellDef>#</th>
    <td mat-cell *matCellDef="let element">
      <span [matTooltip]="'Hello, world'" matTooltipPosition="below"
        >tooltip</span>
    </td>
  </ng-container>

The table can have thousands of rows, that's why I have to use ChangeDetectionStrategy.OnPush. However, with such detection strategy I have a problem with tooltips - they are shown without text. StackBlitz demo is here. Could anyone say how to fix it?
