Short description of error
When modifying any View3D Move Modal Key Configuration sub-options, as soon as anything is modified, entire move view rollout collapses on its own.
Exact steps for others to reproduce the error
1, Go to User Preferences>Input>3D View>3D View (Global)>Move View>View 3D Move Modal
2, Perform any change to View 3D Move Modal, for example adding new item
Result: Entire Move View rollout immediately collapses
Expected behavior: Rollout should remain open
