I agree that the current behavior is not very sensible. I'm not sure what the 
desired behavior is though, if you have any good suggestions, it is certainly 
something that could be fixed.

I wouldn't mind a bug report.

What if all items in the scope become disabled? Should the focus be moved left 
or down? Or should there be an exception: when enabled==false all Keys events 
are ignored but the arrow keys? None of these seems very satisfying.
