The component navigates to the previous/next month but does not select the correct day.

@zernonia This doesn't seem fixed and actually seems worse as it's also buggy when numberOfMonths = 1 now.

Steps to reproduce [numberOfMonths = 1]

1. Navigate to the view showing February 2025.
2. Select the February the 1st 2025.
3. Use the ArrowLeft key.

It selectes January the 28th instead of January the 31st.
