An issue with DateComponents

The expected number of months for the below code should be -48 months. It used to work like this Until iOS17. Now when building with iOS 18 it gives -47 months.

Changing the two dates with one day back works as expected

import Foundation

var calendar = Calendar(identifier: .gregorian)
calendar.timeZone = .gmt

let components1 = DateComponents(
    calendar: calendar,
    year: 2004,
    month: 2,
    day: 29 //28 in case of changing day to 28 it works as expected
)
guard let date1 = components1.date else {
    exit(1)
}

let components2 = DateComponents(
    calendar: calendar,
    year: 2008,
    month: 2,
    day: 29 //28 in case of changing day to 28 it works as expected
)
guard let date2 = components2.date else {
    exit(1)
}

print(date1)
print(date2)
let months = calendar.dateComponents([.month, .isLeapMonth], from: date2, to: date1)
print(months)
