Maya navigation controls do not work as expected while Lock Viewport to Actor is enabled

Maya navigation controls do not work as expected while Lock Viewport to Actor is enabled. The camera appears to behave the same as it would normally, but the actor the viewport is locked to is moved to incorrect locations, rotated oddly, and otherwise does not behave as it would using normal navigation methods.

1. Launch: UE4Editor.exe (any project)
2. Drop an Actor in the level
3. Right-click on Actor->Pilot Actor
4. Alt + LMB + Drag to tumble the viewport
5. Alt + RMB + Drag to dolly the camera
6. Alt + MMB + Drag to track the camera left, right, up, down

Results:
The camera appears to behave the same as it would normally, but the actor the viewport is locked to is moved to incorrect locations, rotated oddly, and otherwise does not behave as it would using normal navigation methods.
