Ben is trying to keep ash specific state out of views. Can you move this where
you need it? Same comment on all the changes you're adding to ui/views.

Not sure I follow. How can I not introduce something to ui/views and at the same
time eliminate ash-specific ifdefs in TabDragController?
I could introduce docked as a property (there is GetNativeWindowProperty) but I
thought you didn't like that approach either.
Or do you mean just moving that chain of invocations to a method in
TabDragController (although then it would need to be ifdefed with USE_ASH)?

Done.
