Is your feature request related to a problem? Please describe.
I want to style range selection with both directions, but days don't have selecting classes with swapRange prop.
How to reproduce:

1. Set selectsRange and swapRange properties
2. Select 25 December 2024 first
3. Try to hover to the date less is selected.
4. Days which include to the range don't have selecting classes

Selecting classes: react-datepicker__day--in-selecting-range , react-datepicker__day--selecting-range-start , react-datepicker__day--selecting-range-end

Describe the solution you'd like
Days should have the selecting classes with swapRange propery
