Kerbal Space Program

The Docking UI rotational controls do not work when SAS is active. Holding in
a staging mode key for the same axis makes them temorarly work until said key
is released.

Steps to reproduce:
1. Rebind the pitch, yaw and roll keys for Staging UI to a key, such as P.
2. Bind the rotation axes for Docking UI to a joystick.
3. Enter a Rocket and switch to the Docking UI.
4. Observe that the Docking UI keys and axis work.
5. Turn on SAS.
6. Observe that the Docking UI rotation keys and axis no longer work.
7. Hold in the key the rotation axes in step 2 was bound to (e.g. P).
8. Observe that the Docking UI rotation keys and axis works.

Expected behaviour:
- Rotation controlls work regardless of whether SAS is active or not.

Actuall behaviour:
- Rotation keys and axes does not work when SAS is active and a Staging
UI key for the same axis is not being held in at the same time.
