Reaching max Pitch and Yaw while piloting an actor will cause the actor to roll randomly

User Description:

When pointing my view straight down or up the rotation values (x and z) go wild, this makes the camera incredibly difficult to use when pointing in any direction as it seemingly just picks a random value as the direction that is up relative to my view although. This also has the effect of making the view uncontrollable when trying to pan using right click and pointing down, the view will shake wildly and often won't move in the correct direction.

1. Create a blank project & open it
2. Go to Modes > Place > Lights > Add a Spot Light to the level
3. Right-click on the spot light > Choose Pilot 'SpotLight'
4. Repeatedly move the mouse forwards and back so the viewport view looks up and down to reach the rotation lock

Results: When the rotation lock is reached, the viewport will start to randomly roll to the left or right each time

Expected: For the pilot view to work the same as the spectate camera in the view port and not roll when the rotation lock is reached
