"Using the wiki page Gantt.feature.TaskNonWorkingTime

if i add a calender with a second interval for a extra holiday one day in the year the taskNonWorkingTime calendar display does not show it in either dispaly more bar or normal

Calendar example:

calendar example 
{
    "id": 2,
    "name": "5 Day WW (M-F)",
    "unspecifiedTimeIsWorking": false,
    "intervals": [
        {
            "recurrentStartDate": "on Monday, Tuesday, Wednesday, Thursday, Friday at 9:00",
            "recurrentEndDate": "on Monday, Tuesday, Wednesday, Thursday, Friday at 17:00",
            "isWorking": true
        },
        {

        "startDate": "2022-8-9 00:00",
        "endDate": "2022-8-10 00:00",
        "name": "Non working day",
        "isWorking": false
    }
]
}

I created a demo https://codepen.io/marciogurka/pen/KKYxVXp and added some screenshots for clarification.

Looks working fine in v6.0.3. Waiting for the customer test case to reproduce the issue.
