DateRangePicker: Focusing Next/Previous year with visibleDuration 2 jumps one month back/forward

### Provide a general summary of the issue here

I am implementing DateRangePicker using `useRangeCalendar` hook. I have two double-arrow buttons , which should control the current focused year. Upon clicking the buttons, i am calling `state.focusPreviousSection(true)`, which works **almost** correctly. I expect it to always just change the year but sometimes (see video) it changes the focused month by one back/forward.

My other settings:
```
const state = useRangeCalendarState({
...props,
locale: locale,
createCalendar: createCalendar,
firstDayOfWeek: "mon",
visibleDuration: { months: 2 },
pageBehavior: "single", // When clicking prev/next month buttons, the calendar will move by 1 month
})
```

Functions called when clicking arrow buttons.
```
const setMonthBack = () => {
state.focusPreviousPage()
}

const setMonthForward = () => {
state.focusNextPage()
}

const setYearBack = () => {
state.focusPreviousSection(true)
}

const setYearForward = () => {
state.focusNextSection(true)
}
```

Buttons for focusing the next/previous month/year

```

```

### 🤔 Expected Behavior?

I expect to just change the year and not focused month.

### 😯 Current Behavior

Sometimes it changes also focused month.

### 💁 Possible Solution

There might be some bug in this settings combination:
```
visibleDuration: { months: 2 },
pageBehavior: "single",
```

### 🖥️ Steps to Reproduce

Use `useRangeCalendarState` with this properties:
```
const state = useRangeCalendarState({
...props,
locale: locale,
createCalendar: createCalendar,
firstDayOfWeek: "mon",
visibleDuration: { months: 2 },
pageBehavior: "single", // When clicking prev/next month buttons, the calendar will move by 1 month
})
```
and call `state.focusPreviousSection(true)` or `state.focusNextSection(true)`

(i tried to change the year also with `state.setFocusedDate(state.focusedDate.add({ years: -1 }))` with same results).

Start at the useRangeCalendarState configuration and the focusPreviousSection/focusNextSection entry points described in the issue. Reproduce with visibleDuration set to two months and pageBehavior set to single, then verify that changing the year leaves the focused month unchanged in both directions.
