In flight records, when padlocked on a plane and the plane leaves allowed distance, leave camera facing the same direction

Type of improvement: 
Flight record usability improvement

Explanation of proposals:
If you're in free camera mode (and possibly other modes) and you are padlock to a plane, I suggest that if the plane flies out of the lock distance that the game should leave the camera facing in the same direction. As it is right now, the camera seems to return to the original view you started from. So let's say I'm facing North and I padlock to a plane to the South. I want to continue watching that plane. If it then flies to the South then flies out of the padlock distance, my camera view will all of a sudden be returned to facing North and I've lost the plane.

Benefits:
It makes viewing flight records easier. If I'm padlocked and watching a plane and it happens to fly too far away from me, it makes sense that the camera should at least stay looking in the same direction that it was at when the lock was lost. It currently defaults back to the view you started from which could be the other direction. It's very jarring and unnatural feeling.
