The app ought to set the callback on creation (that's why it is a property of the spec). And, if this fix is working, then it is clearly being called.

It is allowed even if resize constraints have been set. (And required for some cases by the Mir & Unity8 design doc.)

This is simply fixing a client bug, not working around a server issue.
