I've looked into this a bit more. I thought for a bit that what was
going on here was that slotClose() was eventually sending us to
OkApplyCancelReadOnlyPolicy::input(SMI_CANCEL)
and that is resetting the output state to INITIAL. But I don't see how
that could change the default button, in the sense of Qt. And looking at
the framestack when we hit slotClose(), I don't see any involvement of
anything other than the Qt classes.
