Position and Size attributes of Joystick layers resetting when duplicating

If you edit the size/position/etc. of a Joystick layer and then duplicate the hierarchy containing the Joystick layer, the duplicated Joystick seems to partially revert back to a default state (position: [0, 0] size: [100, 100]). This can cause Joysticks to stack on top of each other if they're stored in a group, since they'll all now be positioned at the local origin.

This can also happen when duplicating artboards, and seems to happen when loading .rev backups too.
