CGImageSourceCreateThumbnailAtIndex() returning wrong width or height resolution

I downsample images using the below code. In the case of 300 dpi JPEG images, the obtained a resized image whose metadata contain a DPIWidth of 300 dpi as expected but a DPIHeight of 72 dpi while the resolution should remain unchanged. The resized image therefore looks stretched vertically in a UIImageView.

I encounter this issue with Xcode 15.2 (15C500b) and iOS 17.2.

Does anyone encounter the same issue?

let maxSize = pwgPhotoMaxSizes(rawValue: upload.photoMaxSize)?.pixels ?? Int.max
let resizeOptions = [kCGImageSourceCreateThumbnailFromImageAlways : true,
                     kCGImageSourceCreateThumbnailWithTransform   : true,
                     kCGImageSourceThumbnailMaxPixelSize          : maxSize] as [CFString : Any]

guard let resized = CGImageSourceCreateThumbnailAtIndex(sourceRef, imageIndex,
                                                        resizeOptions as CFDictionary) else {
       // Could not retrieve primary image
       let error = NSError(domain: "…", code: …, userInfo: […)
       failure(error)
       return
}
