I don't think this is an out-and-out bug... vtkInteractorStyle is 
responding to TimerEvents from your repeating timer and rotating the 
camera before State is changed in OnLeftButtonUp.

Its probably better to observe the TimerEvent being invoked from 
vtkInteractorStyle rather than vtkRenderWindowInteractor...
you can use HandleObserversOn() and handle idle events from there if you 
like. This means the vtkInteractorStyle wont be executing OnTimer() in 
response to your repeating TimerEvents.

I've amended your test code as an example, its attached.
