Local rotations of an actor instance's components are incorrect in the level editor

Local rotations of components are inconsistent between the Level editor and the SCS editor. The SCS editor rotates the transform widget's coordinate system to match the selected component in FSCSEditorViewportClient::GetWidgetCoordSystem, and FLevelEditorViewportClient::GetWidgetCoordSystem does not. This can be problematic if you have a hierarchy of SM components that you want to pose on a per instance basis in the level.  

• Add an actor instance to a level that contains StaticMesh Components.
• Change to local space transforms using the World/Local space toggle button on the level viewport toolbar.
• Double click a Static Mesh Component, or select a Static Mesh Component in the Details tab and apply a rotation.
• Note that the rotation widget resets to world space after after the rotation is applied rather than being aligned with the component's new rotation.
