Instead of this, I could add a bool flag to setFocusedFrame about whether or not
it should fire these events.  A separate function seemed more readable though,
and it matches what FocusController already exposes.

I think this is fine: it's pretty subtle though. Maybe something to keep in mind
for potential future naming improvements.
