Setting rowHeaderWidthAutoFit to true doesn't work if rowHeaderColumns ist set

Hi,
I noticed, that the row headers width isn't adjusted automatically, if the set the rowHeaderColumns

schedulerConfig: any = {
    rowHeaderColumns: [
      {
        display: "name",
        title: this.dialogTextService.getTranslation('TitCareResponsibleGroups')
      }
    ],
    rowHeaderWidthAutoFit: true,
}

Is this a bug or by design?
