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)
]

Commencez par reproduire la configuration rangebreaks signalée dans une application Dash et inspectez la console du navigateur lorsqu’un jour férié en semaine est inclus. Suivez l’échec depuis le chemin doAutoRange du bundle async-plotlyjs ; le travail est terminé lorsque le jour férié du vendredi est masqué sans le TypeError, tandis que les exclusions des week-ends et des heures continuent de fonctionner.
