[REACT] Gantt doesn't highlight Saturdays and Sundays

[greg]

I have a simple gantt with a basic calendar:

calendars: {
    rows: [
      {
        id: "general",
        name: "general",
        intervals: [
          {
            recurrentStartDate: "on Sat at 0:00",
            recurrentEndDate: "on Mon at 0:00",
            isWorking: false,
          },
        ],
        expanded: false,
      },
    ],
  }
  ...
  project: {
    calendar: "general",
  }

I tried more different calendars, but they all renders on the grid in the same way:

I wish the weekends to be higlighted as you can see here:

Could you advise how to achieve it, please?

Could you please attach your full test case so that we can run it and debug it?
