Short description of error
Seems an area light resize in the 3D view is not registered with the undo system.
Exact steps for others to reproduce the error
- Add an area light to the scene
- Grab and move somewhere else
- Change size with widget
- The light is now back at the origin with the default size
Note that when changing the size using the properties panel an undo *will* work correctly, i.e. only change back the size.
