Observe:
- SnapOnEnable is checked
- When disabling the LazyFollow, rotating the camera, then enabling, the position snaps correctly but the rotation does not (and then drunkenly rotates to the correct orientation)
- This does not occur with rotation mode set to "Follow".
There are many scenarios where this is more pronounced (i.e. when doing a full 180, it comes in and does a flip!)
