SceneKit objects become sharp when viewed through non-opaque objects with depth of field enabled

By adding this code to the default SceneKit Xcode project, one can reproduce the issue (the default ship object is blurred when viewed directly by the camera, and sharp when viewed through the semi-transparent square):

Code Block cameraNode.camera!.wantsDepthOfField = true
cameraNode.camera!.focusDistance = 2
cameraNode.camera!.fStop = 0.5
let plane = SCNNode(geometry: SCNPlane(width: 1, height: 1))
plane.position = SCNVector3(x: 0.5, y: 0, z: 13)
plane.opacity = 0.5
scene.rootNode.addChildNode(plane)

Code Block
cameraNode.camera!.wantsDepthOfField = true
cameraNode.camera!.focusDistance = 2
cameraNode.camera!.fStop = 0.5

let plane = SCNNode(geometry: SCNPlane(width: 1, height: 1))
plane.position = SCNVector3(x: 0.5, y: 0, z: 13)
plane.opacity = 0.5
scene.rootNode.addChildNode(plane)

Is this something expected, and is there a workaround for making objects seen through semi-transparent objects appear blurred as well?
