Double-clicking on a camera, which normally takes you to its location, also rotates the camera so that it faces whatever direction you were facing in the viewport prior to clicking on the actor in the world outliner.
Occurs only in 4.9.1. Does not occur in 4.8.3 or Main CL: 2700641
1. Open editor
2. Open any project
3. Add a camera to the level
4. Rotate yourself so that you are facing a different direction than the camera
5. Double-click the camera in the world outliner
Result: Camera rotates to match your original rotation in the viewport
Expected: Viewport would take you to the camera and match the camera's rotation.
