Photo disappears and flashes loading indicator when presented

[bachonk]

To replicate

let photo = AXPhoto(attributedTitle: NSAttributedString(string: "Sent by \(comment.name)"),
                        attributedDescription: nil,
                        attributedCredit: nil,
                        url: URL(string: comment.attachmentURL!))

let transitionInfo = AXTransitionInfo(interactiveDismissalEnabled: true, startingView: cell.imageAttachmentView) { [] (photo, index) -> UIImageView? in
                // this closure can be used to adjust your UI before returning an `endingImageView`.
                cell.imageAttachmentView
}

let dataSource = AXPhotosDataSource(photos: [photo])
let photosViewController = AXPhotosViewController(dataSource: dataSource, pagingConfig: nil, transitionInfo: transitionInfo)
self.present(photosViewController, animated: true)

What happens Photo disappears and loading indicator shows briefly.

What should happen Initial photo should remain while the other photo is loading to prevent flashing screen.
