Why does the Controller ControlRotation limit roll values to between -90.0f and 90.0f?

While the Yaw and Pitch values for ControlRotation in Controller can be modified to any value, the Roll values can only be between -90.0f and 90.0f. I’ve been searching for where these values are maintained but I cannot seem to find it in code. How would I remove this so that Roll is not limited to this range.

EDIT: So it turns out that its only the camera view that is limited to -90.0f and 90.0f once it pulls the information from the controller. In that case, the same still applies. How can make it so that the camera view does not have this limit?
