Scene events issue?

[keasy9]

I have two scenes. Both of them has HTML-based UI, so I need to hide scene UI when scene deactivated. Also both scenes has loaders, and when I'm changing scenes via Engine.goToScene('newScene') things hapening in this order:

1. previous scene disappeared
2. loader for next scene starting
3. loader for next scene finished
4. previous scene deactivation event fired
5. next scene appeared

But I expected that order:

1. previous scene disappeared
2. previous scene deactivation event fired
3. loader for next scene starting
4. ...

Is this a bug or my expectations wrong?
