holidays on week days behave incorrectly

Hi Folks,

I am having issues when I have holidays on week days.
if I exclude weekends and have a holiday on Friday there is a bug

rangebreaks=[
    # NOTE: Below values are bound (not single values), ie. hide x to y
    dict(bounds=['sat', 'mon']),  # hide weekends, eg. hide sat to before mon
    dict(bounds=[18, 9], pattern='hour'),  # hide hours outside of 9.30am-4pm
    dict(values=["2021-04-02", "2021-12-25"]),  # hide holidays (Christmas and New Year's, etc)
]

Bắt đầu bằng cách tái hiện cấu hình rangebreaks đã được báo cáo trong một ứng dụng Dash và kiểm tra console của trình duyệt khi có ngày lễ vào ngày trong tuần. Truy vết lỗi từ đường dẫn doAutoRange của bundle async-plotlyjs; hoàn tất khi ngày lễ vào thứ Sáu bị ẩn mà không có TypeError, trong khi các loại trừ cuối tuần và giờ vẫn hoạt động.
