MKMapRect.contains() returns false when crossing 180th meridian using .union()

Classification:Bug Reproducible:Always
When using `MKMapRect.union()` to merge two `MKMapPoint`s (one on either side of the 180th meridian / antemeridian, resulting in a rect that should cross it), calling `.contains()` on the unified rect returns false for a point that is within the rect, rather than true.

import CoreLocation
import MapKit

let southWest = MKMapPoint(CLLocationCoordinate2D(latitude: -15.597850272465658, longitude: 166.90067687320118))
let northEast = MKMapPoint(CLLocationCoordinate2D(latitude: 76.42715026767411, longitude: -90.1312509710639))
let size = MKMapSize(width: 0, height: 0)
let rect = MKMapRect(origin: southWest, size: size).union(MKMapRect(origin: northEast, size: size))

let containedPoint = CLLocationCoordinate2D(latitude: 33.083100, longitude: -117.05982)
print(rect.contains(MKMapPoint(containedPoint))) // false, but should be true

Expected: MKMapRect.contains() to return true in the above example
Actual: False is returned
Very similar to, though this is using newer APIs.
