ag-grid loses focus after refresh

I'm using ag-grid in Angular 4.x. Whenever the grid is refreshed it loses focus. This seems to be a bug in ag-grid.

Is there any workaround, like setting the focus back to the grid, so that keyboard navigation still functions?

Here is my solution:

   private bringFocusBack() {
      let cell = this.gridOptions.api.getFocusedCell();

      if ( cell ) {
         this.gridOptions.api.setFocusedCell( cell.rowIndex, cell.column );
      }
   }

Call this method after doing the refresh:

this.gridOptions.api.refreshRows( rowsToRefresh );
this.bringFocusBack();
