For certain videos, `- [AVMutableVideoCompositionLayerInstruction setCropRectangle:atTime:];` behaves weirdly.

For example: `[layerInstruction setCropRectangle:CGRectMake(0, 0, assetTrack.naturalSize.width, assetTrack.naturalSize.height) atTime:kCMTimeZero];` could cause half of the content being cropped when the final `AVComposition` is played in an `AVPlayer`.
