Thomas, thanks for the suggestion. I thought I had tried that and indeed, when I attempted to disable focus reporting within tmux there wasn't any change. I'd have to guess that tmux is intercepting the control sequence and probably discarding it. I don't know enough about terminal emulation to say if that's a sane thing to do.
In any case, I'm told in #tmux on freenode that focus reporting can be disabled in tmux 1.9, so it's just a matter of waiting for that release (or building the latest sources). Thanks again!
