Does 'firstDay# not work with resourceTimeline

[JenniferSchoen]

I've tried changing my calendar to a different type and then it works but it won't change anything for the resourceTimeline.

My Code (svelte):

[...]
let options = {
        view: 'resourceTimelineMonth',
        url: [...],
        eventSources: [...],
        resources: [...],

        hiddenDays: [6, 0],
        firstDay: 2,
        duration: {days: 14},

[...]
    };

Everything else, aside from the firstDay, works.

firstDay option makes sense when displaying weeks. But in month mode, days are always displayed from the first day of the month. firstDay does not affect the monthly view.
