ag-Grid: tried to call sizeColumnsToFit() but the grid is coming back with zero width, maybe the grid is not visible yet on the screen?

@HostListener('window:resize')
onResize() {
  if (!this.gridApi) return;

  setTimeout(() => {
    this.gridApi.sizeColumnsToFit();
  });
}

window.addEventListener("resize", function () { ...

<ag-grid-angular 
  ...
  ag-grid-resize       <============
>
</ag-grid-angular>

import { Directive, HostListener } from '@angular/core';

@Directive({
  selector: '[ag-grid-resize]'
})
export class AgGridResizeDirective {
  private gridApi;

  @HostListener('window:resize')
  onResize() {
    if (!this.gridApi) return;

    setTimeout(() => {
      this.gridApi.sizeColumnsToFit();
    });
  }

  @HostListener('gridReady', ['$event'])
  onGridReady(params) {
    this.gridApi = params.api;

    params.api.sizeColumnsToFit();
  }
}
